Factory Infiniti exhausts are engineered to be exceptionally quiet and compliant, relying on restrictive crimped piping, heavy resonators, and dense mufflers. This factory design builds backpressure and traps heat, directly stifling the true mechanical output of your 3.5L or 3.7L V6. Upgrading to our Infiniti exhaust systems solves this problem by introducing smooth, mandrel-bent stainless steel piping designed to increase exhaust gas velocity and clear the combustion chamber faster.
Whether you are replacing a restrictive factory setup with a high-flow Y-pipe on a modern G37, installing race headers to extract maximum high-RPM horsepower, or bolting on a full G35 catback exhaust with burnt tips, we have the exact hardware for your chassis. Each component is engineered to provide a direct-fit replacement for your OEM setup.
These exhaust components are built for DIY tuners, weekend mechanics, and performance enthusiasts wanting measurable gains in horsepower, torque, and throttle response. For maximum engine efficiency and a complete air-flow overhaul, we highly recommend pairing your new exhaust system with a high-flow cold air intake.
Will a catback exhaust cause a check engine light?
No. Modifying the exhaust system from the catalytic converter back (catback) does not alter the primary emissions sensors, meaning your engine's ECU will not throw a check engine light.
Do these exhaust systems fit Nissan Z models?
Yes. Because the Infiniti G-series and Nissan Z-series share the exact same FM platform and VQ engine architecture, many of our Y-pipes, race headers, and exhaust kits act as direct cross-compatible upgrades for both the 350Z and 370Z.
