Product Details

The Flowmaster American Thunder axle-back exhaust system is built to give your vehicle a deep, aggressive exhaust tone and a cleaner, more performance-oriented look at the rear. This axle-back muffler kit replaces the factory rear section of the exhaust (the muffler and tailpipe) and includes exhaust tips for a finished appearance.

Key Features:

  • Aggressive, deep sound: Tuned to produce a muscular, throaty exhaust note under acceleration while staying comfortable at cruising speeds.
  • Flowmaster muffler technology: Flowmaster is known for its performance mufflers, which are designed to improve exhaust flow compared with restrictive factory mufflers.
  • Durable construction: Built from corrosion-resistant steel for long service life.
  • Includes exhaust tips: Tips give the rear of the vehicle a more custom, performance-focused look.
  • Bolt-on axle-back design: Installs in place of the factory rear exhaust section, with no cutting or welding of the front exhaust components.

Flowmaster has been a trusted name in performance exhaust for decades. The American Thunder line is a good choice if you want better sound, improved exhaust flow, and sharper styling with a straightforward upgrade. Select the correct option for your application from the variants listed.
