Product Description

**This is a SPECIAL ORDER : Made to order item. Each order is handled individually, wait times from 2-4 weeks should be expected on all Fast Intentions exhaust components. Wait times may vary depending on production volume.**

Fast Intentions is proud to present our 370Z Resonated High Flow Cats.

These resonated high flow cats are the premier upgrade for all 370Z owners looking to maximize the performance from their VQ37VHR V6 engine. Our resonated high flow cats effectively increase low end torque and maximize power throughout the entire RPM band. Your overall exhaust volume will increase, while creating a deeper and smoother tone.

Built as a direct OEM replacement, resonated high flow cats are designed to be an addition to your cat back exhaust system. We maximize performance by increasing the tubing diameter, using a less restrictive catalytic converter, and adding straight through perforated core resonators to free up back pressure. This application is recommended for the enthusiast who wants to remove their OEM catalytic converters, but keep the sound level to a minimum. This is our quietest option available.

PRODUCT INFO

  • Direct OEM replacement; no cutting or welding required.
  • 2.5" T-304 mandrel bent stainless steel tubing.
  • The catalytic converter is a 300 cell metallic core incased within a spun stainless steel shell.
  • 49 state OBD II compliant.
  • 8" perforated core resonator constructed of T-304 stainless steel with a 2.5" inside core and a 3.5" outside case.
  • 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.
  • Limited 3 year warranty on all welds and craftsmanship.
  • Application Specific: 2009+ Nissan 370Z Base, Sport, Touring & NISMO.
  • Compatible on Left and Right Hand Drive vehicles.
  • Gaskets, hardware and installation instructions are included.
  • Hand built in the USA.

BENEFITS

  • An increased average of 24 rear wheel horsepower & 17 foot pounds of torque in conjunction with our cat back exhaust system.
  • Refining the factory exhaust note by increasing depth and volume.
  • Reduction in EGT's (Exhaust Gas Temperature) by freeing up back pressure.
  • Weight: 15 lbs. (7 lbs. lighter than the factory catalytic converters.)

Works great, clocked decent power on the dyno after tune. Wishing I went with test pipes now that the car is on e85 though. But e85 retunes are expensive so I don't really want to swap these out.

PERFECT HI-FLOW CATS I have 370z 2012 , cats paired with catback from nismo After initial break-in , the exhaust gave off a lot of white smoke :) But after 1 hour cooling everything was OK , no smoke , no fuel smell , no CHECK ENGINE light Impressive increase of performance ! I 'm still smiling while driving :)

Very high quality welds joining sections of sturdy 304 stock. Paired with an Ark Grip catback exhaust, the tone is been deepened without any increase in rasp thanks to the integrated resonator. The distinctive change in tone at 3500rpm VVEL actuation is more accentuated. Smell test is marginally worse than OEM on a cold start but sounds incredible, and is not any more apparent to the nose than OEM at operating temperatures. Fitment is near OEM, excluding the deletion of a structural brace that fastened the OEM catalytics to the subframe (FI RHFC does not have mounting points to fasten to the brace). There is slight concern of sagging weight over time and what that could incur in terms of exhaust leak from stressed flanges, but I have experienced no issues with leaks or scrapes in this area at all. Don't forget to follow the break-in procedure as is for any aftermarket catalytics to ensure the substrate can adequately expand, adhere, and cure to the cat housing.

Very well made. Fit perfect. Sound and performance is exactly what I was looking for. I have a 13 370Z . Been running it hard. No CEL light.
