ISR Performance Combo 350Z Y Pipe and GT Single

The ISR Performance Combo Y-Pipe and GT Single Exhaust for the Nissan 350Z is a bundled exhaust package combining the ISR Z33 Y-pipe with the ISR 350Z GT Single catback exhaust. Saves 5 percent vs purchasing both parts separately and gives you a complete mid-pipe-back single-exit exhaust path in one order.

What It Does

The Y-pipe and catback are the two halves of a complete 350Z exhaust upgrade behind the headers. Buying them together as a combo saves 5 percent vs ordering individually and ensures matched components designed to work as a system - the Y-pipe steps to the catback inlet correctly and the single-exit catback gives the car a deep, refined tone profile with less highway drone than dual-exit alternatives.

Combo Contents

• ISR Performance Y-Pipe for 350Z / G35 RWD (IS-Z33-Y) - mid-pipe with twin 2.5 inch runners merging to 3 inch single pipe
• ISR Performance GT Single Exhaust for 350Z (catback) - single-exit catback with 4.5 inch polished tip

Critical Fitment Note

RWD ONLY. The Z33 Y-pipe in this combo will NOT fit AWD G35X variants. For G35X exhaust upgrades, use the Z34-based combo path with IS-Z34-Y.
