I'm looking for an aftermarket replacement for my Y-pipe since mine needs to be replaced, and I can't seem to find any performance orientated ones that actually fit the X models. Anyone know any good ones?

 

I can’t confirm this, but I believe that there are y pipes that are made for the awd g37. There shouldn’t be any reason that they wouldn’t fit the awd G35. This is a picture of an aftermarket y pipe on an awd g37.
