ISR Performance ST Exhaust - Nissan 370Z

ISR Performance is known for making well-built exhaust components for the tuner market. This ST Cat-Back exhaust system is designed specifically for the Nissan 370Z, aiming to improve the sound and flow of your Z's exhaust system. It replaces the factory muffler and piping from the catalytic converter back, giving your car a more aggressive tone and potentially freeing up a bit of horsepower by reducing backpressure.

This system is constructed from durable 304 stainless steel, which is chosen for its resistance to corrosion and its ability to withstand the high temperatures found in an exhaust system. The ST series is designed to offer a noticeable, sporty sound without being overly raspy or obnoxious, making it a solid option for daily driving or spirited track use. The piping diameter is optimized to work well with the 370Z's engine, ensuring good scavenging and exhaust gas velocity. Installation typically involves unbolting the stock system and bolting on the new ISR components, though some minor adjustments might be needed for perfect alignment.

When installing this cat-back system, you'll want to have a good set of wrenches and possibly some penetrating oil for stubborn factory bolts. It's a direct bolt-on replacement for the factory exhaust from the catalytic converters back. You'll notice a deeper, more resonant exhaust note that really lets the V6 engine sing, especially under acceleration. This system is a popular choice for 370Z owners looking for an improved exhaust note and a cleaner look under the car.
