These pipes are called: catless race pipes, test pipes, race pipes, or just cat deletes; no matter what you call them they do just one thing, make power. The TurboXS 03-06 350Z & 03-07 G35 Race Pipes provide the ultimate in performance for your 350Z or G35. The pipes are made from heavy gauge 304 Stainless Steel with thick flanges for perfect fitment and sealing. The pipes can be used with the TurboXS 350Z Cat back Exhaust, other manufacturer's cat back exhausts, or they can be use on their own as a direct replacement for the factory cat pipes.

I hooked these up to my AAM Competition 3 inch MaxFlow Single Exhaust Systems, connected with a ISR performance Y pipe and the sound is by far the sweetest sexiest Deep Loud Growl I’ve ever heard. I think I’ve turned more heads in a week then a screw could turn all his life. I’ve added so much to the motor that I can’t tell directly how much Hrspwr it added but I know for sure that it added a good bit.
