ISR Performance Exhaust Y-Pipe - Nissan 370z / G37

The ISR Performance Exhaust Y-Pipe for the Nissan 370Z and Infiniti G37 is a stainless steel replacement for the factory Y-pipe that improves exhaust tone, ground clearance and performance. It picks up at the 2-bolt catalytic converter flanges and carries both banks of the VQ37VHR back to a high performance velocity merge before stepping up to the rear exhaust flange.

Design and construction

• 2.75 inch stainless steel piping from the 2-bolt cat flanges to the merge
• Bellowed flex sections in each runner to absorb engine movement
• High performance velocity merge collector
• Steps to 3 inch stainless piping from the merge to the rear 3 inch exhaust flange
• Integrated dimpled gusset plate ties the two runners together for strength and rigidity

Why the merge matters

The Y-pipe is where the two banks of the VQ meet, and a sloppy merge costs both flow and sound. ISR's velocity merge keeps the exhaust moving cleanly into the single 3 inch section, which contributes to the deep tone this Y-pipe is known for. The gusset plate addresses the cracking that plagues lesser Y-pipes with unsupported runners.

Fitment
