OK i have a G35 6mt and my wife have a FX and her exhaust is rusted like crazy is i was thinking about swapping my BORLA exhaust and buying me a new 1 but will it fit

 

Old or new FX? In either case, the FX is based on an extended FM platform so it's all in the same family. With some welding extension and finagling, it might be possible. You'll probably get better info on a dedicated FX forum.

 

Ok thanks
