Product Details

The Flowmaster American Thunder Axle-Back Exhaust System is a performance axle-back muffler and exhaust kit. It replaces the factory rear exhaust section to give your vehicle a deeper, more aggressive tone and a modest improvement in exhaust flow. The American Thunder line is Flowmaster's moderately aggressive sound option, so you get a noticeable exhaust note without the extreme volume of Flowmaster's louder lines.

Key Features:

  • Axle-back design replaces the rear section of the exhaust behind the rear axle
  • Flowmaster's tuned muffler technology produces a deep, muscular exhaust tone
  • Improved exhaust flow compared with restrictive factory mufflers
  • Durable construction built for long service life in daily driving and spirited use
  • Designed as a bolt-on upgrade, so installation is straightforward for most DIYers and shops

Flowmaster is a well-known American exhaust brand, and its mufflers are widely used by truck, muscle car, and performance enthusiasts. Choose the option that matches your application to upgrade both sound and appearance. Alternate names for this product include axle back exhaust kit, rear exhaust kit, and performance muffler system.

Very helpful

The part is as advertised and is an exact fit. Very fast shipping with great communication. Will use them again when I need boat parts.

Nice tires

A dealership broke one of the parts of a rim I have on a car and needed a part in a pinch! Price was great and shipping was incredibly fast! Really happy with the selection and listing such a specific part, other sites just listed part numbers without pictures so THmotorsports made it easy to trust.

Lovely experience would definitely buy again
