ISR PERFORMANCE 350Z Y PIPE
I swapped out my stock Y-pipe for this ISR unit and I can say the fitment is great and it looks bad ass with that support piece welded to the collector. I was running test pipes with a Vibrant muffler and Vibrant resonator. I did notice that the exhaust note sounded better under 2,500 rpms and got raspier over 2,500 rpms. I don't know if its because the stock y-pipe is made of thicker metal. Either way I still like it and it does sound great driving around town.
