    Fast Intentions is proud to present our Q60 3.7L Traditional Cat Back Exhaust System.

    This cat back exhaust system is the premier upgrade for all Q60 coupe owners looking to maximize the performance from their VQ37VHR V6 engine. Our 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. All of our exhaust components are T-304 stainless steel with 2.5″ tubing that is mandrel bent to maximize exhaust flow and efficiency. The X Pipe is designed to increase low end torque and maximize power throughout the entire RPM band. This exhaust system is unobtrusive at idle and cruising speeds; but comes to life at wide open throttle. The addition of this exhaust system will improve the aesthetics of your vehicle with its sporty and classy appearance. In terms of overall sound, this cat back is our quietest option available.
