ISR Performance Exhaust Y-Pipe (03-09 Nissan 350Z /Infiniti G35) IS-Z33-Y

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.
