ISR Performance Exhaust Y-Pipe - Nissan 370z / G37 (Non AWD X Models)

Upgrade exhaust flow, sound, and performance with the ISR Performance Exhaust Y-Pipe for Nissan 370Z, Infiniti G37, G35X, and Q60 3.7L. Engineered for enthusiasts who demand maximum efficiency without sacrificing fitment or affordability, this high-performance Y-pipe is a proven upgrade for both daily-driven and performance-built vehicles.

Constructed from durable stainless steel, the ISR Performance Y-Pipe features 2.75-inch mandrel-bent piping from the catalytic converter flanges, flowing smoothly through bellowed flex sections that help reduce vibration, stress, and exhaust movement. These flex sections improve longevity while maintaining excellent ground clearance—ideal for lowered or aggressively driven vehicles.

At the heart of the system is a high-performance velocity merge, where the dual runners transition into a 3-inch stainless steel outlet. This design significantly improves exhaust scavenging, throttle response, and overall power delivery while producing a deeper, cleaner, and more aggressive exhaust tone. An integrated dimpled gusset plate ties both runners together, increasing structural rigidity and ensuring long-term durability under hard driving conditions.

Designed to balance performance, sound quality, and value, the ISR Performance Y-Pipe delivers noticeable gains in exhaust flow while maintaining compatibility with most aftermarket cat-back exhaust systems. Whether you’re naturally aspirated or running forced induction, this Y-pipe provides the unrestricted flow needed to support horsepower gains.
