Fast Intentions Full Downpipes (full cat delete) – Infiniti Q50 / Q60 VR



Fast Intentions is proud to present our Infiniti Q50 Sedan & Q60 Coupe VR30DDTT Full Downpipes.

Our full downpipes unleash the performance of your VR30DDTT twin turbo V6 engine. Effectively increasing low end torque and maximizing power throughout the entire RPM band. The exhaust volume will increase inside and outside the vehicle.

Built as a direct OEM replacement, full downpipes are designed to be an addition to your cat back exhaust system. We maximize performance by replacing the OEM secondary and primary catalytic converters and increasing the tubing diameter to 3.0″.

  • Direct OEM replacement; no cutting or welding required.
  • Lower factory mounting brackets are retained and in OEM location.
  • 3.0″ mandrel bent T-304 stainless steel tubing.
  • CNC lathe cut 304 stainless steel v-band flanges, for a seamless restriction free connection from the OEM turbocharger exhaust housings.
  • All factory v-band clamps and hardware are retained.
  • 3/8″ thick mild steel flanges. All flanges are bright nickel plated 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.
  • J-bend style O2 sensor bungs are welded in factory location for a plug-n-play install of your rear OEM O2 sensors.
  • Full stainless steel construction, including the substrate which is furnace braised to the mantle for outstanding durability.
  • Unique end-cap design locks substrate in so it can’t rattle around.
  • Limited 3 year warranty on all welds and craftsmanship.
