I have Fast Intensions resonated test pipes running with the GTM stage 1 SC. They work great together (no codes and nearly 8psi). Getting the cats out of the way gives the car a sweet exhaust note (I still have the stock Nismo exhaust after the TP's). The exhaust smell is more pronounced, but not obnoxious. You also get a sweet back pressure growl when you downshift.
