Whats going on, I'm kind of stuck on what I want to do. I have B5 and want to put an exhaust on it but don't know what to do. I've looked at all the duals and I havent found one I like. Well i found an S4 with a single 4 in and I was hooked. I want to do a custome single back into two chrome tips. The thing I cant decide on is the pipe diameter. Im going to be chipped this spring and I did the piggies. Any ideas on pipe size?

 

I have a single 3" borla exhaust. GURUMAN has a 4" on his GT28 car, but for 99% of applications thats overkill and is just gonna hang down really far. If your set on single id go with 3 or 3.5".

Im going to ditch my borla for a twin 1

 

Im planning on running a straight it just sounds mean.

 

this is just bad *** http://www.youtube.com/watch?v=VvS2eMXUsr8&NR=1

 

Go with a single 3.5, no muffler, no cats. You will love it, and it will spit hot fire.

 

I like where your going thanks guy

 

You should have picked up my old exhaust. I sold exactly what I had described before .... for a whopping $350!

 

damm that would of been perfect

 

I did a custom daul 2.5" into a 3" for all the flow. Consider putting in electric dumps too, cause its electric and even more bad ***!
