no, its not. 2.5" max. 2" for true duals. 3" is far too large for 99% of the people on this board.
Thanks...I think stazi will be on tomorrow and give a more technical reason while making a fool out of said poster. But of course he will come up with some reason why he needs 3" exhaust.
I think the only one with 3" exhaust NA is Dale Kortes...but he made 210whp with his 3L so
