Sounds proper to me! Dam close to rightgeous

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?

stoopid 56k... still waiting to hear it! i want to get the twicepipes system but i'm afriad it might be too loud. since i put the k&ns on it's pretty deep when i get on it.

**edit** just watched the short one. nice! sounds very yummy. i think i might have to get it!

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 wizz 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!

....It is cheaper and better to have a reputable muffler shop bend aluminized pipes to connect between the header/manifold and the muffler.

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"

:stupid:

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!

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.
