I ran a 3" as straight as I could from the turbo to a cheap turbo muffler on the rear, through a 3" resonator.
Its so quiet I can hear the belt tensioner while driving, the electronics in the trans pan at idle, and the car next to me's stock exhaust.
3" cutout is going right behind the trans pan, going to try to keep it pointed to the rear.
Will do a dyno open/closed, tune for open obv. and expect a fairly sizable difference between them. However still expecting something with it closed.
It just means more when you are passing with it closed, then open it to let them know whats up, the eyebrow raising at how much more you had left to go and what it was you had all that time. Even better when the car originally came with a 160hp 4cylinder lol. cant resist... too good... must idle around... looking for trouble
