Size Of Downpipe And Exaust
#11
[quote name='Cheers!' date='Mar 25 2005, 07:35 PM']unless you know an excellent exhaust shop or can do it yourself, I have no seen that many well done exhaust systems in toronto area. If i were doing a custom exhaust, i would buy the turbo back racing beat system, sell the downpipe, and have that part custom made to fit your needs.

If you just wanted a straight 4" system then look into getting a diesel muffler or two.
On the two 3" pipes out the back, yes they are alot louder than i would have expected. I am gonna be getting another set of mufflers to put inline right before the ones i have on there now to help quiet it down. Personally i dont care about how loud it is, what bothers me is all the new attention the cops give me for jsut driving. I would hate to see there reaction if they heard the open wastegate.
I wanna leave it vented to the atmosphere but might look into a little exhaust system of its own to help reduce noise, cause it carries a ways!
For future reference i would recomend a 4" to 2.5" if your concerned about noise. Oh and also i wouldnt recomend the N1 style mufflers of off ebay either.
But if noise isnt a problem then go with exactly what i got. Even my Vette friends say my car sounds good now.
edit: Oh and if you have the time and money buy a welder and the exhaust tubing online and make a system your self. Thats the only real way i found to get what i wanted.

well I ask cause it seems the 4 from 3 is all the rage and yes i get tired of not hearing my three amps and subs.
geting ready to make the piping and was wondering what I will replace the Drager with.

i plan on using a couple extra magnaflows. As for wanting a straight through 4" system, if you had the room you can order there diesel mufflers anywhere from 20" to like 36" i think. Check out magnaflows website for details but i believe you could make it plenty quiet with there selection. If worse comes to worse then just buy two and put them inline.

This is a S4 13BT mild streetport, 60 trim turbo, 3" DP > 3" MP. The exhaust is GP Sports. The flange on the Y-pipe is stock sized because it was sold as a cat-back. But the Y-pipe is 80mm or ~approx 3 inches. I guess it's kinda loud, when I crank it up I can hear loud pulses. But I gassed it in front of a cop (he was 2 cars behind me, I didn't know), redlined 1st, and for some reason I just decided to put it in 4th. My speed @ redline was ~approx 40MPH, and the speed limit was 40MPH. The cop just drove beside me and looked at me funny. So I guess its not as loud as I think. I'm going to weld a Borla XR-1 muffler in there to see what it does tho.

[quote name='spooliNrx7' date='Apr 16 2005, 06:52 PM']Why not go 4 inch downpipe with a 3-1/4 to 3-1/2 split in the y pipe? I always thought you wanted to have larger down pipe and then a smaller diameter for split duals.

The outlet on my turbo is 3 inch. There's no point in putting a 4" DP. Plus it's more work, and I'm lazy as ****.
