Project G37 Sedan Fast Intentions Exhaust

The Fast Intention Resonated High Flow Cat compared to stock.  The J bend anti-fouler is used to prevent check engine lights.

 

High Flow Cat System Highlights:

  • Direct OEM replacement; no cutting or welding required
  • The catalytic converter is a 300 cell metallic core incased within a spun stainless steel shell
  • 3/8″ thick mild steel flanges. All flanges are bright nickel plated to eliminate potential corrosion
  • J-Bend style O2 sensor anti fouler to ensure the check engine light stays off
  • Weight of 15 lbs total which is 7 lbs lighter than factory catalytic converters
The high flow resonated cats were a last minute decision we made not wanting to leave that horsepower on the table.
Moving on to the mufflers.  Everything about this system screams quality right down to the beefy exhaust hangers

  1. in the videos were the cars non resonated or 18in resonator, im looking to buy one and am just concerned the 18inch resonator will be to quiet and the non resonator will have to much drone and lose the deep sound. if you could get back to me thatd be great thanks.

  2. We got the 18″ resonators on the 2.25″ exhaust. The resonators are shown on page 2 of the article. I love the exhaust. It’s quiet enough when I’m cruising around on surface streets or on the highway but there’s nothing quiet about it once your over 4k RPM’s. On cold startup my neighbors definitely hear the car. It’s the perfect compromise in my opinion compared to other louder exhausts that sound great when you’ve got your foot stuffed on the go fast pedal but make you hate the car when you’re just driving normally.
