TDX Cat Back Exhaust System

The Fast Intentions TDX Cat Back Exhaust System is a premier upgrade for 2009-2021 Nissan 370Z models (Base, Sport, Touring & NISMO) seeking to maximize performance from their VQ37VHR V6 engine. This system is meticulously crafted with 2.5" T-304 mandrel-bent stainless steel tubing and features 3/8" thick mild steel flanges, bright nickel plated to prevent corrosion and port-n-polished for smooth flow. The system includes standard 6" x 14" round polished stainless steel perforated core mufflers and 4.5" dual wall, resonated, polished stainless steel exhaust tips. For those seeking further customization, optional carbon fiber mufflers and 100-cell Mil Spec race catalytic converters (which reduce raw fuel smell with minimal performance impact) are available. The X Pipe section can be optioned with non-resonated or 12" or 18" resonated stainless steel perforated core resonators, designed to reduce interior noise without sacrificing performance. Installation is straightforward as a direct OEM replacement, requiring only simple hand tools with no cutting or welding necessary. The lowest point of the exhaust system remains at the same level as the OEM configuration. The system includes all necessary gaskets, hardware, and installation instructions. It is compatible with both Left and Right Hand Drive vehicles. This exhaust system offers significant performance benefits, including an average increase of 20 rear wheel horsepower and 11 foot pounds of torque over the factory exhaust. It refines the factory exhaust note by increasing depth and volume, and helps reduce Exhaust Gas Temperatures (EGTs) by freeing up back pressure. The stainless steel construction with optional carbon fiber mufflers results in a lighter system, weighing 41 lbs with CF mufflers and a 12" resonated X pipe (16 lbs lighter than factory), or 47 lbs with SS mufflers and a 12" resonated X pipe (10 lbs lighter than factory).
