OEM Part Numbers

• Infiniti G37 Infiniti 20050-JK60B

This OEM part number applies to the factory Y-pipe and resonator assembly on the G37 V36 platform. The ISR IS-Z34-Y replaces this assembly. Buyers can verify their specific OEM part number using the Infiniti or Nissan parts catalog with their VIN, as part numbers may vary between coupe, sedan, and convertible body styles.

Pairs well with:

• ISR GT Single Muffler Catback Exhaust Infiniti G37 Coupe RWD (2008-2013) The ISR catback is the natural downstream companion for this Y-pipe. Installing the ISR Y-pipe and ISR catback together creates a complete matched ISR exhaust system from the catalytic converter outlets to the muffler tip for maximum flow and consistent tone character throughout.
• Injen Cold Air Intake Infiniti G37 Coupe (2008-2013) Polished or Black A cold air intake to complement the Y-pipe upgrade, improving intake airflow to balance the improved exhaust flow on the VQ37VHR.

The ISR Performance G37 Y-pipe utilizes 2.75" 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 2.75 inch primary runners from each catalytic converter merge into a single 3 inch outlet at the velocity merge, stepping up pipe diameter for improved exhaust flow. Bellowed flex sections on each primary runner absorb engine movement and vibration, protecting the welds and the catalytic converter flanges from stress fractures. The dimpled gusset plate ties the two primary runners together before the merge for increased structural rigidity. This Y-pipe replaces the factory Y-pipe and resonator assembly and bolts directly to the existing 2-bolt catalytic converter flanges. No emissions equipment is altered, replaced, or removed. All gaskets and hardware for installation are included. ISR designates this product for off-road and competition use only. 

The ISR Performance Y pipe was designed to provide the best possible exhaust tone, ground clearance, and performance, all at an affordable price!
