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. |
