Stainless Steel Y-Pipe with Bellowed Flex Sections

The ISR Performance Y-pipe is engineered using 2.5-inch stainless steel tubing that transitions to 3-inch tubing after a high-performance velocity merge. It incorporates bellowed flex sections to absorb engine movement and an integrated dimpled gusset plate for increased rigidity and strength. It runs from the 2-bolt catalytic converter flanges back to the rear 3-inch exhaust flange. Included in the box are the Y-pipe, two 2.5-inch exhaust gaskets, one 3-inch exhaust gasket, and all necessary bolts and nuts for installation. This Y-pipe is specifically designed for Nissan 350Z and Infiniti G35 models. However, it will not fit on X model AWD G35 vehicles.
