I searched and didnt find much. Im trying to look for what other 20bs sound like. Im having problems getting mine to sound good. I was running 3" pipe all the way back but since Ive gotten geared up for turbo and changed the back to 4" -> dual 3" the car sounds bad. Im running 1x4" to 2x3"and it just sounds raspy. Like a ricey honda. Is it possibaly the transition to the 4" from the 3" downpipe?
This exhaust trail and error thing is starting to get annoying.
Any real help would be appreciated.
PS all mufflers are straight thru.

Use just 1 pipe SS and 4" and you will get the sound back.....if you like the sharp sound then don´t use any mufflers, otherwise 2 small 4 inch mufflers, makes the car sound like a mean monster trying to breath...;-)
