i have an 05 coupe...i've been shopping around for an exhaust and iv narrowed it down to invidia...i want the n1(i hear its louder than the g200) but from what i can see it is for the 350z. i don't see why it wouldn't work on the g but i need to be sure before i spend the money. from what i've been reading all that i require is an extension pipe. if that is the case where do i get it or is this something the shop that puts it on can do.

 

ghetto but a muffler shop can weld the extension on...
