    Default Finally, my Twice Pipes exhuast system is installed.. but problems.. Pics inside

    Well.. after attemping to install this exhuast by my self, it was obvious that that Twice Pipes exhuast setup from MSA did not line up with the stock muffler mounts, did not fit snug into the body, and needed custom fabrication.

    I took my car to Meineke Muffler and they installed it for... ehh... $150 for 3 hours of work.

    They tried lots of combinations and twisting it, and everything they could to make the exhuast fit up tight and snug...

    but this POS setup from MSA hangs wayy to low, and actually touches my tireand is VERY close to the tire, and you can see that it has touched the tire and there is melted rubber on the pipe.

    Is there anything I can do about this???

    Sorry to hear about your troubles, but how does it sound?

    I have a version of twice pipes on my 73 and its loud and resonates badly around 2700 RPM. It does get lots of compliments on the sound though. Ferrari-like.

    actually inside the car.. it sounds like a V8 honestly... at low RPM's...

    and it does resonate around 3,000 RPM...

    I noticed that at higher RPM's, it doesn't really sound ferrari like .... like evryone says.. but is loud, and kinda has "farts" which i hope will go away after the fiberglass burns out a bit.

    I have a BIG video of a bunch of different angles and my driving by... but it's like 40 MB... i'll upload it tonight

    BTW also when I drive it hard... and let up off the gas quickly... you can kinda hear popping or gurgling... almost like a small backfire...

    am I running to rich?

    No, that sound means your driving a sports car. There is no cure once it get's into your bloodstream.

    BTW - Negitive function on the Video so far. I'll admit Ryan, I can't wait to see/hear it!

    Downloading the video now! Awesome speed... Looks like you only have 2 resonators (one for each pipe) on your system... I'm sure that would be very LOUD. I had a single lukey muffler and it was very loud... ! Awesome sound though

    MSA exhaust systems are not bolt on systems as advertised in their catalogue. The pipes on my 2.5 inch system would not even fit together and had to be resized. One of the pipes was trashed since the bends were not even close to make it fit properly. Your system may sound nice but you are doomed to catastropic failure with the pipes hanging that close to the ground. It is cheaper and better to have a reputable muffler shop bend aluminized pipes to connect between the header/manifold and the muffler.

    Excellent sound! Did not like the dragging look of them under the car--one speed bump and it's all over...Has anyone been able to get them to fit stock mountings?

    Default msa for me too

    i have that system and i had a hell of alot of problems with it too. I also have msa's header so nothing fit right... but yeah i took mine to a custom exhaust fabricator and he made it fit nicely under mine for 100$ and took him an hour. That was about 6 or 7 months ago. After that much time the exhaust sounds much different then yours. Still as loud or maybe even louder but it gets a much deeper tone going. I think it sounds really nice up at around 7000rpm and the v8 sound at idle is cool everyone gives you a second look, heh. But anyway i like the sound of yours hope you enjoy it. BTW that exhaust is not car alarm friendly so try not to piss too many people off. later... cool ride.

    i just need to figure out a way to move the exhuast AWAY from my tire!

    I am getting melted rubber on my exhuast when i make hard right turns... grr!

    i went to midas and checked to see what it would cost to do an exhaust system from the header back and they said $400-$500! but that included a flowmaster muffler with all 2.5".

    as for how to get it away from your tire, did you try adjusting the bracket to pull it away? you may have to jiri-rig it, but i know what a pain it is to have your tire melt off on your exhaust pipe..

    *edit... btw, what are the diameters of the pipes? i looked on MSAs website and they didn't say.... also, are you running stock manifold, 3 into 2, or 6 into 1 header? just curious...

    each are 2" inches in diameter...

    so technically it's a 4" exhuast setup....
    but because of the 2 - 2" inch pipes doesnt flow as well as a 4"

    Yup, I had problems with my exhaust (not MSA though) hanging too close to the ground - especially in the middle of the car when you go over speed bumps or driveways. To make things worse, the exhaust system was in two halves linked with a U-bolt at that middle point, so the bolt used to hang down a bit.
    One day I was driving a FAT friend out of his driveway, and the bolt caught on the steel track running across his driveway. BANG! Back half of the exhaust was pulled off, and had to get the exhaust shop to put it back. Nasty business, and well worth spending a bit extra to avoid IMO!

    but because of the 2 - 2" inch pipes doesnt flow as well as a 4"

    That should be looked at in terms of cross-sectional area of the pipe(s). The area of a circle is pi*r^2, so the combined area of your two 2" pipes is approximately

    (3.14 * 1^2 ) * 2 pipes = ~6.28 square inches

    for a single 4" diameter pipe

    3.14 * 2^2 = ~12.56 square inches

    incidentally, for a 2.5" pipe

    3.14 * 1.25^2 = ~4.91 square inches

    and 2.25"

    3.14 * 1.125^2 = ~3.97 square inches

    That is of course a very crude way of looking at the issue of exhaust flow and besides getting an overall feel for the dimensional comparisons, is probably not important at all when compared to all the other factors involved.

    However,
    In regards to area in a single pipe setup your exhaust would be equivalent to :

    sqrt( 6.28 / 3.14 ) = r = 1.414"

    r*2 = diameter = 2.83"

    Hmmm...I could be wading into a deep pile of ^&$$^% here, but...
    I thought flow rate was more than just function of cross-sectional area. I seem to remember Poiseuille's Law which (admittedly dealt with fluid dynamics) stated that flow rate was directly proportional to r^4 and inversely proportional to length of pipe. Big short pipes flow better than long skinny ones, and exhaust flow rate is a major component in motor power. Because all the 240z headers I have seen go down to a single pipe (even MSA's 3 into 2), the limiting factor becomes the radius of that tube, not how many you split into downstream. I presume the flow rate through the one pipe is equal to the flow rate of the six individual header pipes (engineers are pretty smart about this), so as long as your tailpipe isn't smaller, I wonder how much benefit a bigger sized exhaust actually has. Seems to me the better way to go (ideally) is to bore out your exhaust ports and fit them with an oversized header.

    I think.

    Wow, sounds like you guys had lots of problems... I guess I shouldn't have taken my system for granted! 2.25" header back with a Lukey muffler (I have not heard a better muffler on a Z yet) for $240 Aussie and never had any problems with speed bumps. My suspension was at the stock ride height, though.

    I too bought the MSA 6:1 header and premium 2 1/2" pipe system and had problems getting things to fit. Got my independant local muffler guy to do the work and add a glass pack to knock the noise down a little - my neighborhood doesn't have much of a sense of humor.

    You should call Sal at MSA (x201 if I remember correctly) and work something out. I would have been happiest if it had all bolted up as advertised, but in the end Sal made it right.

    Default Twice pipes

    Hi I'm a little late into this thread but I think the Twice pipes are supposed to be over and under not side by side that might be part of your problem..
    I also wanted MSA Twice Pipes but read you had to cut a little of the rear valence..I wasnt going to do that to a virgin 71 240 so I had a muffler shop build me a system over and under with glass packs or he called them resonators..said they wouldnt blow out...
    Anyway I love them people always seem to know I'm on my way ..Guys on bikes look over say nice car nice sound ..around idle i rumble like a motorboat.. get on up about 2700-3500 and who needs a horn...by the way I dont have a radio in the car driving this way about 2yrs( who needs one)..
    Good luck Dave

    the resonators aren't properly named. They're called EXPANSION CHAMBERS, and are designed to trap the exhaust/sound of certain frequencies to 'resonate' inside and cancel themselves out. there's nothing inside but space for the pulses to bounce. Modern mufflers are designed with suchchambers inside, and so they are bigger in size, but the older/sporty cars use them to decrease backpressure & make more power while keeping the exhaust tube size small.

    Well..

    the exhuast shop tried to have the pipes go Up and Down... instead of Side by Side... but the Muffler had mounts to bolt onto for it to be upright.... and the tips are angled upward as well.
    So if I put the pipes Up and Down, the tips would be facing left or right... and wouldn't look right.

    I would try to adjust em myself now.. but the damn exhuast shop welded everything together.

    I LOVE the sound... but I don't like how low they sag, and it's side profile.

    If it was more tucked in.. it would be PERFECT

    The twin pipes on the works rally cars didn't cut the rear valence.
    Perhaps, you can get them placed higher up?

    alright.. well I went back down and pushed and moved and shoved my way around.

    The reason why it was soo close to my tires and it was sitting too low was because the IDIOTS at Midas....

    Didn't tighten the bolts all the way.. and the ones they did tighten, they were at horrible angles.

    Everything is fixed now... still a bit low.. but no tire rubbing... no vibrating... not as much scraping...

    Overall.... I give the sound a 9 out of 10 (very loud, but sometimes annoying)
    Install ease ... 5 out of 10 (too much adjustment and bad fit no matter what)
    Powergains .... 7 out of 10(felt a good power gain not as much as expected)

    NOTE : This is the Twice Pipes on my 280Z ... the install and fit and power will be different for a 240Z without a doubt.. since the setup was designed for a 240Z not a 280z

    So what do you think is the best possible exhaust kit you could get for the 280?

    Default Exhaust

    i FINALLY GOT MY Z GOING BUT THE EXHAUST WAS SHOT. i COULDNT GET A REPLACEMENT FROM THE LOCAL FOREIGN PARTS DEALER AND WENT TO mIDAS. tHEY USED MY EXISTING HEADER AND BENT NEW 2 INCH PIPE AND ADDED TWO BULLET RESONATORS IN SERIES. oNE IN THE MIDDLE AND ONE AT THE REAR. tHE PROBLEM i HAVE IS THAT I KEEP GETTING LEAKS AT THE INTERFACE BETWEEN THE MANIFOLD AND THE HEADER. THE GASKETS I GOT ARE APPROXIMATEY 1/16 INCH THICK AND THIS IS MY SECOND GASKET AND IT STILL LEAKS AT THE INTERFACE. tHE SOUN IS GREAT EXCEPT FOR THE LEAK. iS THERE A THICKER GASKET AVAILABLE? aNY AADVICE WOULD BE APPRECIATED.

    Contact MSA at 800-633-6331 for a gasket specifically for headers.

    Also, if the leak is in one of the corners of a port, you may have an alignment problem that a thicker gasket will have a hard time fixing. I had to lift my header from the back end before tightening the flange nuts to solve a leak.

    Default Twice pipes exhaust system

    240Zman

    Thanks for the reply. I sent for a new gasket from courtesy parts in Texas. I think I have the same problem you had. The muffler tech has the back end too tight and the interface at the header is not parallel. When I get the new gasket I will have him try to tighten it up before he sets the rear end supports. He may have to bend the header pipe to get it aligned right.
    I wpuld have fixed it myself but at 74 years old I am avoiding going under the car.

    Thanks

    You should call Sal at MSA (x201 if I remember correctly) and work something out. I would have been happiest if it had all bolted up as advertised, but in the end Sal made it right.
    Same here. Sal made it right. I am going to add the glasspack Friday to knock down the resonance some.

    i'm definitely going to be buying the msa twice pipes next week ^_^

    anyone heard of Richard's Performance Muffler in Vista, Ca? I had the exhaust on my supra done at the local Midas and they did a good job of modifying it to fit but it sounds like this setup is a litttttle more complex than the average Blitz cat-back. Any input would be appreciated :P

    I'm one of the very few people running the MSA 2x pipes setup on a 2+2. I had to have a foot long section welded in to make it fit the longer chassis, but I am happy with the way it mounts up. It does hang a bit low, especially on my car, which is lowered with Tokico springs and running a shorter-than-stock wheel/tire combo. Speed bumps are a real hazard for me, and I occasionally even scrape a tad on more pronounced hi-speed highway dips.

    Be warned, this setup is LOUD. Almost V8-ish at idle, and the resonances are a bit strong in the 2-3K range, but there is nothing like the scream when you're WOT and pulling through 6K. Truly an intoxicating sound! The backfires and burbling when you close down the throttle is a plus in my book too.

    I would be remiss if I failed to mention that it can be tiresome over long drives, especially since the car is turning over 4K on the Interstates (no OD and 3.545). But it suits my driving habits well. It sure does wake me the hell up on the drive to the office!

    I should post a sound clip, I'll see if I can put one together over the weekend.

    well, loud is what i want ^_^ and i figure if it comes to the point that i REALLY want to do something about it, i could always just add a couple more glasspacks and that should quiet it down. but from what i've heard on some videos, this system sounds downright sick!!! what till they see my stock looking Z come roaring past them :P

    Default Is this as good as it gets?

    Powergains .... 7 out of 10(felt a good power gain not as much as expected)

    Are you running headers with this setup? I looked at an earlier photo and it seemed that you're only running the stock exhaust manifold.

    If so, why did you leave it on without replacing them with headers? Cost?

    Could that be the reason why you didn't get the power improvements you were expecting?

    Why did you spend the money on a system that you felt wasn't designed for your car or engine size? Did you not consider just going to a good exhaust shop and asking them to build you an exhaust system you should have got in the first place?

    Sorry man, I don't want to sound like a PITA but I'm not convinced your convinced that you got what you paid for! So how would you sum up your experience and what would have done differently if you could have started over?

    Hey guys. Jus got the twice pipes installed yesterday. let me tell you...horrible horrible fit. the head pipe and the y-pipe were great but everything from that back didn't line up and was at an angle. of course this is AFTER the guy removed my stock system so he was either going to charge me 150 to put my stock exhaust BACK on or another 100 to modify the kit and make it work. he basically made his own bends from his straight pipes and connected them to the glasspacks. took him around 3 hours

    BUT after that, i got to fire it up for the first time. OH MY GOSH!!! what a sound!! even the mechanic was greatly surprised haha. it does resonate from 2-3k but nothing that really bothers me. and once you get up to 4k and above it's jus pure heaven

    so in my mind...if i can get the extra 100 back from msa it's a good deal...if not...i'm greatly disappointed that they won't stand behind their product. so be warned...you may have troubles with this system. i even called ahead and asked if there was any problems i should be aware of but of course they said no. anywho, i'll post a video when i get a hold of a camra

    Are yall having trouble out of the header or the whole system? How does the header fit? I ordered a 3-2 header and I'm nervous as to how it will fit.

    am I running to rich?
    Unfortunately you can't achieve that true, vintage, ferrari-like sound with a turbo.
    Happens best when using triple Mikunis or Webers.
    In my former 2.4L set-up I ran DCOE40's, MSA 6into1 header, and twice pipes. (fitting problems too)
    I currently have a 2.8L, stock SU's (running rich) MSA 6into2 header and 2.5" custom system with a Borla XR-1 muffler. (tucked nicely)

    If I can just figure out how to get the mini DVD posted.
