Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers a performance upgrade with an aggressive sound and improved exhaust flow. Engineered for enthusiasts seeking both power gains and a commanding exhaust note, this system features mandrel-bent tubing and Flowmaster's proven Super 40 Series muffler technology.

Key Features:

  • Super 40 Series performance muffler delivers moderate to aggressive exterior exhaust tone
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for optimal flow
  • Dyno-tuned design maximizes horsepower and torque gains
  • Connects directly after factory catalytic converter for true cat-back configuration
  • Utilizes factory hanger locations for precise fitment and easy installation
  • Includes all necessary hangers and hardware for bolt-on installation
  • Backed by Flowmaster's 3-year limited warranty

This American Thunder system provides the perfect balance of performance and sound, giving your vehicle a deep, aggressive tone without excessive drone. The mandrel-bent construction ensures smooth exhaust flow, while the durable aluminized steel construction provides long-lasting corrosion resistance.

Very happy with my recent order.

Very Good

Easy checkout through PayPal.

Ordered two oxygen sensors but only one was shipped even though two were listed on the packing slip. I called customer service. A second sensor arrived two days later.

Fast shipping . Would do business again

Easy to order

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.

Quick and easy!

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!!
