Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers a perfect balance of performance and sound for enthusiasts seeking enhanced exhaust flow without excessive noise. This complete bolt-on system features Flowmaster's 70 Series performance muffler, engineered to produce a moderate exterior exhaust tone that's aggressive enough to be heard but civilized for daily driving.

Key Features:

  • 70 Series performance muffler for optimal flow and moderate sound
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for maximum exhaust velocity
  • Large 3.50-inch polished stainless steel tip adds a premium finishing touch
  • Dyno-tuned design maximizes horsepower and torque gains
  • Utilizes factory hanger locations for precise fitment
  • Includes all necessary hangers and hardware for straightforward installation

Flowmaster's mandrel-bending process ensures smooth internal tube surfaces and consistent diameter throughout the system, eliminating restrictive crush bends found in lesser exhaust systems. The Force II system is designed for quick weekend installation using common hand tools, with no cutting or welding required on most applications.

so far so good. will let you know more once product arrives

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

easy to find site

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.
