The ISR Performance 350z / G35 Y-pipe utilizes 2.5" stainless steel piping along with bellowed flex sections running from the 2 bolt catalytic converter flanges back to the high performance velocity merge. The Y pipe then steps to 3" stainless piping coming out of the velocity merge to the rear 3" exhaust flange. The Y pipe also features an integrated dimpled gusset plate tying the two individual runners together for increased strength and rigidity.
The ISR Performance Y pipe was designed to provide the best possible exhaust tone, ground clearance, and performance, all at an affordable price!
What’s in the box:
1x 350z / G35 Y-pipe
2x 2 bolt 2.5” exhaust gaskets
1x 2 bolt 3” exhaust gasket
6x bolts

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.
