Complete Cat-Back Exhaust System:

This is a complete cat-back exhaust system that replaces everything from the catalytic converters to the rear exit. The cat-back design means you retain the factory catalytic converters, maintaining emissions compliance while upgrading the exhaust flow and sound. The complete system includes all necessary piping, muffler, and hardware for a straightforward installation.

Single Exit Design:

The single exit design routes exhaust out one side of the vehicle, creating a distinctive, asymmetric appearance. This design is popular in the tuner community for its unique look and is reminiscent of classic Japanese performance cars. The single exit also provides weight savings compared to dual exit systems and can offer slight packaging advantages. The design delivers an aggressive, sporty appearance that sets your G37 apart.

Mandrel-Bent Stainless Steel Construction:

The exhaust uses mandrel-bent stainless steel piping throughout. Mandrel bending maintains consistent pipe diameter through bends, unlike crush bending which creates restrictions. This consistent diameter ensures smooth exhaust flow and minimizes backpressure. The stainless steel construction resists corrosion and maintains its appearance over time, even in harsh climates with road salt. The quality construction ensures long service life.

Improved Flow and Power Gains:

The larger diameter piping and mandrel bends reduce exhaust restriction compared to the factory system. Reduced backpressure allows the VQ37VHR engine to breathe more freely, resulting in measurable power gains. Most users report 10-15 horsepower gains at the wheels, with gains increasing when combined with other modifications like intakes and headers. The improved flow also enhances throttle response throughout the RPM range.

Aggressive Exhaust Note:

The ISR GT exhaust delivers an aggressive, deep exhaust note that enhances the VQ37VHR's naturally good sound. The exhaust is noticeably louder than stock, with a sporty tone during acceleration and a pleasant rumble at cruise. The sound is aggressive without being obnoxious, making it suitable for daily driving while still turning heads. The single exit design contributes to the unique exhaust note.

Direct Bolt-On Fitment:

The exhaust is designed as a direct bolt-on replacement for the factory system, using the factory mounting points and hangers. This ensures proper fitment and eliminates the need for cutting or welding. The direct fitment also means the exhaust can be removed and the factory system reinstalled if needed. All necessary hardware and gaskets are included for a complete installation.
