Product Details

The Flowmaster 817213 American Thunder Cat-Back Exhaust System delivers an aggressive exhaust tone and maximum performance for enthusiasts seeking a bold sound and increased horsepower. This complete cat-back system is engineered with precision mandrel-bent 16-gauge stainless steel tubing to maximize exhaust flow and reduce backpressure, while the dyno-tuned design ensures optimal power gains across the RPM range.

Key Features:

  • Super 44 Series performance mufflers for aggressive exterior exhaust tone
  • Mandrel-bent 16-gauge stainless steel tubing for superior flow and durability
  • 304 stainless steel tailpipes resist corrosion and maintain appearance
  • Dyno-tuned configuration for maximum performance gains
  • Uses factory hanger locations for direct bolt-on installation
  • Includes all necessary hangers and hardware for easy installation
  • Backed by Flowmaster's Lifetime Limited Warranty

The American Thunder series is designed for muscle cars and performance vehicles where an aggressive sound and maximum power are priorities. The Super 44 mufflers produce Flowmaster's most aggressive sound level while maintaining excellent exhaust scavenging for performance applications. This system installs easily using factory mounting points and includes everything needed for installation.

The best& very fast!

Great product info and fast shipping!

Easy to order, excellent sale price with free ground shipping.

It was really a easy way to order this battery for my son. I'm so glad that it worked out to order it and hope he will get the battery real soon. I wasn't wanting to pay extra for shipping.

Nice and simple ordering

Vary good thank you.

Look forward to receiving this

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.

great
