Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust note while maintaining a moderate exterior tone. This complete bolt-on system connects directly after the factory catalytic converter and features Flowmaster's Super 50 Series performance muffler for improved flow and power.

Key Features:

  • Super 50 Series performance muffler for optimal flow and moderate sound level
  • Mandrel-bent 16-gauge stainless steel tubing for maximum exhaust flow
  • Large 3.00-inch polished 304 stainless steel tips for a premium appearance
  • Two tailpipe exit configurations available for customized installation
  • Utilizes factory hanger locations for straightforward bolt-on installation
  • Includes all necessary hangers and hardware for complete installation
  • Backed by Flowmaster's Lifetime Limited Warranty

Engineered for enthusiasts seeking improved exhaust flow and a refined aggressive tone without excessive volume, this cat-back system delivers both performance gains and enhanced sound character. The mandrel-bent construction ensures smooth bends that maintain consistent tubing diameter throughout, reducing backpressure and maximizing horsepower and torque gains.

Good business

It was awesome

great

Great fast service

Good shopping experience.

I needed a power steering cooler and I found what I think will work. The price was good but shipping was high.

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

Good

Everything went good, order shipped out the next day. The prices were good but the shipping cost was way to high $25 dollars for 2 head gaskets and some bolts oil pan bolts.

great shipping time and ordering process; great customer service
