Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust note for enthusiasts seeking both power gains and improved sound. This complete cat-back system is engineered with mandrel-bent tubing to maximize exhaust flow and reduce backpressure, resulting in measurable horsepower and torque improvements.

Key Features:

  • Super 50 Series performance muffler delivers a moderately aggressive exterior exhaust tone
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for optimal flow
  • Dyno-tuned design ensures maximum performance gains across the RPM range
  • Utilizes factory hanger locations for secure mounting and proper fitment
  • Includes all necessary hangers and hardware for straightforward installation
  • Backed by Flowmaster's 3-year limited warranty

This American Thunder system provides the perfect balance between performance and sound, offering a deeper, more aggressive tone without excessive cabin drone. The precision-bent tubing and quality construction ensure long-lasting durability and consistent performance. Installation is designed to be straightforward, using existing factory mounting points for a secure, factory-quality fit.

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

Great service so far

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.

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!!
