Frequently Asked Questions

Question Answer
Will this fit the G37 Coupe? No, this exhaust is specifically engineered for the G37 Sedan chassis. The piping length and hanger positions are different for Coupe models.
Is this compatible with AWD (G37x) models? Yes. The ISR Single GT is designed with clearance to fit both Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD/G37x) Sedan configurations.
How loud is the Single GT exhaust? This is an aggressive, high-flow system. It produces a deep, throaty VQ growl and is louder than the factory exhaust. It is ideal for enthusiasts wanting a race-inspired tone.
Does it include hardware? Yes, the kit comes complete with the necessary gaskets and bolts required for a direct bolt-on installation to your existing factory or aftermarket Y-Pipe.
Will this cause a Check Engine Light (CEL)? No. Since this is a catback system that installs after the catalytic converters, it will not affect your emissions sensors or trigger a CEL.
