Fast Intentions is proud to present our Infiniti Q50 & Q60 3.0L / Nissan Z Lower Downpipes. Our lower downpipes unleash the performance of your VR30DDTT twin turbo V6 engine. Effectively increasing low end torque and maximizing power throughout the entire RPM band. Your overall exhaust volume will increase but keeping the interior noise resonance under cruising speeds at a reasonable level. Built as a direct OEM replacement, lower downpipes are designed to be an addition to your cat back exhaust system. We maximize performance by replacing the OEM lower catalytic converters and increasing the tubing diameter.


  • Direct OEM replacement: no cutting or welding required.
  • All factory mounting brackets are retained and in OEM location.
  • 2.50" mandrel bent T-304 stainless steel tubing keeps interior noise resonance to a minimum.
  • 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.
  • Threaded O2 sensor bungs come standard and are welded in factory location for a plug-n-play install of your rear OEM O2 sensors.
  • Lower downpipes are sold as a set of 2: Left / Right
  • Limited 3-year warranty on all welds and craftsmanship.
