I'm kind of in the same boat as Baddadiam. I have an '07 ZX4 with the 2.3 Duratec and the only exhaust I can find from FS is a 2 1/4" which would require mods to fit the factory body kit. I was just on the Borla site and it says they don't have any part #'s for the '07 yet. I'm adding a stage 2 FS turbo kit so I'd like to go at least 2.5" diameter, don't really care if it's stainless or not.
Help!
