to put things into perspective, im making 250rwkw now and might be increasing to about 280 soon,
I have a 3" turbo back exhaust atm, I was thinking of leavin the first section of the exhaust as is and maybe having a 3.5" catback made up implementing the largest 2 mufflers, that way the extra 0.5" diaemeter will make up for the restriction of the mufflers......
Anyone know any exhaust shops in inner melbourne that could look after me?
cheers
