Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust note for truck and SUV applications. This complete bolt-on system is engineered to increase horsepower and torque while reducing exhaust backpressure for improved throttle response and fuel efficiency.

Key Features:

  • Mandrel-bent 16-gauge aluminized steel tubing maximizes exhaust flow and resists corrosion
  • Moderate exterior exhaust tone provides a deeper, more aggressive sound without excessive cabin drone
  • Dyno-tuned design optimized for maximum performance gains across the RPM range
  • Direct bolt-on installation uses factory hanger locations for a secure, OEM-quality fit
  • Includes all necessary hangers, clamps, and hardware for straightforward installation
  • Backed by Flowmaster's 3-year limited warranty for quality assurance

This Cat-Back system replaces exhaust components from the catalytic converter outlet to the rear exit, providing a complete performance upgrade. The precision mandrel-bent tubing maintains consistent pipe diameter throughout each bend, eliminating restrictions and turbulence found in crush-bent systems. Professional installation recommended for best results.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

very fast processing received product within a few days. fair prices. will do business with again.

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

I was looking for some new lowering springs for my Integra and after looking around I found this place to be the best price around. It got here a week later which didn't seem to bad. Got the tracking info after 2days. Overall it was great shopping experience. They helped me and replied quick to the questions I had.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
