What are your plans, NA or FI? Are you look'n for sound or performance or both? http://forums.listentomyexhaust.com/ should give you and idea of what the sounds are like. Good thing to look for in exhausts are the material made *ie Aluminum or stainless steel* the size of piping. I suggest Mugen hahahaha and I've heard good things from Evo and Thermal. Good luck

 

i have the N1 and i like it. It actually has a coating on the piping back to help keep it in good shape
