    Fast Intentions is proud to present our 370Z TDX 2.5″ Cat Back Exhaust System. This Cat Back exhaust system is the premier upgrade for all 370Z owners looking to maximize the performance from their VQ37VHR V6 engine. Our cat back exhaust system will enhance the sound that Nissan 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 aggressive appearance.


    • Direct OEM replacement: no cutting or welding required.
    • 2.5″ T-304 mandrel bent stainless steel tubing.
    • Standard 6″ x 14″ round polished stainless steel perforated core touring mufflers.
    • Optional 6″ x 10″ round polished stainless steel perforated core sport mufflers.  This option is 15 – 20% louder than our standard touring muffler.
    • Optional 100-Cell Mil Spec race catalytic converters built within the exhaust system lead pipes. An ideal option when combined with our long tube headers: 100 cell “race” catalytic converters will reduce the raw fuel smell while having little to no effect on performance.
    • 4.5″ dual wall, polished stainless steel exhaust tips.
    • Optional 4.5″ dual wall, Prismatic (Tri Color) stainless steel exhaust tips. Prismatic Tip Disclaimer
    • 3/8″ thick mild steel flanges. All flanges are bright nickel plated to eliminate potential corrosion.
    • All flange connection points are precision Tig welded around the outside.  The inside is sanded down and port-n-polished for a smooth exhaust flow.  This process reduces exhaust turbulence at the flange connection points.
