ISR Performance Series II - GT Single Exhaust System - Non Resonated - 89-94 Nissan 240sx (S13)

If you're looking to give your 89-94 Nissan 240sx (S13) a more aggressive exhaust note and improved flow, the ISR Performance Series II GT Single Exhaust System is a solid option. This cat-back system replaces your factory exhaust from the catalytic converter back, designed to enhance the sound and performance of your S13's engine.

This particular version is the non-resonated model, meaning it skips the resonator. This choice leads to a louder, more direct exhaust tone that many enthusiasts seek for their performance builds. The system is constructed from durable stainless steel, which helps resist corrosion and ensures it holds up over time. Its single-exit design offers a cleaner, more focused look compared to some dual-exit systems, and it's built to fit right onto your S13 without requiring extensive modifications.

When installing this system, you'll want to ensure you have the necessary hardware. While this cat-back system is designed as a direct replacement for the factory exhaust, it's always a good idea to inspect your existing hangers and connections. The goal here is to get a more pronounced exhaust sound and potentially a slight improvement in exhaust gas scavenging, which can contribute to better throttle response.
