Fast Intentions is proud to present our Gen 2 G Sedan Cat Back Exhaust System. This cat back exhaust system is the premier upgrade for all 2007-2013 Sedan owners looking to maximize the performance from their VQ35HR 3.5L V6 or VQ37VHR 3.7L V6 engine. Note: This cat back exhaust system is not compatible with the 2003-2006 G35 sedan. Our cat back exhaust system will enhance the sound that Infiniti created from the factory by making it deeper, smoother, and louder. Built as a direct OEM replacement, our exhaust system is easy to install with simple hand tools; no cutting or welding required. Our X Pipe is designed to increase low end torque and maximize power throughout the entire RPM band. The exhaust note is unobtrusive at idle and cruising speeds; but comes to life at wide open throttle. With the addition of our cat back exhaust system, you will improve the aesthetics of your vehicle with its sporty and classy appearance.
