Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers aggressive performance and sound for enthusiasts seeking maximum power gains with that signature Flowmaster rumble. This complete exhaust system is engineered to replace everything from the catalytic converter back, providing a straightforward upgrade that transforms your vehicle's exhaust note and performance.

Key Features:

  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for improved exhaust flow
  • Polished stainless steel tips add a premium finishing touch
  • Dyno-tuned design maximizes horsepower and torque gains
  • Deep, powerful exterior exhaust tone delivers authentic muscle car sound
  • Specially tuned resonator controls interior drone for comfortable highway driving
  • Utilizes factory hanger locations for precise fitment
  • Includes all necessary hangers and hardware for straightforward installation

Flowmaster's mandrel-bent construction ensures smooth bends without crimping or restrictions that rob power. The American Thunder series strikes the perfect balance between aggressive sound and livability, making it ideal for daily drivers who demand performance without excessive cabin noise. The aluminized steel construction provides excellent durability and corrosion resistance, while the polished stainless tips resist discoloration and maintain their appearance.

awesome dealer ..... easy site to search.... fast shipping

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.

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!!
