Fast Intentions Catback Exhaust – Infiniti Q50 Sedan



The Fast Intentions catback exhaust system is the premier upgrade for all G37 owners looking to maximize the performance from their 3.0TT, 2.oL TT, 3.5L Hybrid, or 3.7L engine.  The exhaust system will enhance the sound that Infiniti created from the factory by making it deeper, smoother, and louder.


  • Direct OEM replacement; no cutting or welding required.
  • 2.50″ mandrel bent T-304 stainless steel tubing keeps interior noise resonance to a minimum.
  • 5″ x 9″ oval, 14″ long polished stainless steel perforated core mufflers.
  • 4.5″ dual wall, resonated, polished stainless steel exhaust tips.
  • Optional 4.5″ dual wall, non-resonated, prismatic (tricolor) stainless steel exhaust tips.
  • Front flanges are 3/8″ thick mild steel with a bright nickel plated finish to eliminate potential corrosion.  All flanges are welded on the inside, sanded down and port-n-polished for a smooth exhaust flow. This process greatly reduces exhaust turbulence at the flange connection points.
  • Slip fit connection points utilize Torca Accuseal clamps.  They are a simple and effective way to connect exhaust system components.  Unique seal and high clamp loads are provided without permanently distorting the exhaust components, allowing the flexibility to disassemble for service.
  • Non resonated or 14″ stainless steel perforated core resonators within the X Pipe. Resonators reduce interior noise without affecting performance.
  • Limited 3 year warranty on all welds, craftsmanship, mufflers and tips.
  • Application Specific: 2016 Infiniti Q50 Sedan VR30DDTT (Premium, Sport & Red Sport)
  • Compatible with the 2WD (Rear Wheel Drive) and AWD (All Wheel Drive) models.
  • Gaskets, clamps and hardware are included.
  • Hand built in the USA.


  • An increase in performance throughout the entire RPM band. The largest gains recorded were: 16 horsepower at 4,800 RPM / 30 foot pounds of torque at 3,800 RPM.
  • Refining the factory exhaust note by increasing depth and volume.
  • Reduction in EGT’s (Exhaust Gas Temperature) by freeing up back pressure.
