Product Details

The Flowmaster Super 40 Series Chambered Muffler delivers an aggressive, deep exhaust note that's perfect for enthusiasts seeking maximum sound and performance. This muffler uses Flowmaster's original two-chamber design to produce a loud, attention-grabbing tone while maintaining excellent exhaust flow for high-horsepower applications.

Key Features:

  • Aggressive, deep exhaust sound with noticeable interior resonance
  • Two-chamber design maximizes flow for high-performance vehicles
  • Fully welded 16-gauge 409 stainless steel construction for long-lasting durability
  • Ideal for muscle cars, trucks, and high-horsepower street machines
  • Easy to install with universal fitment options

The Super 40 Series is Flowmaster's most aggressive muffler, delivering maximum sound and performance. The chambered design eliminates internal packing materials that can degrade over time, ensuring consistent performance and sound for years. Note that this muffler produces significant interior cabin resonance, making it best suited for drivers who want an aggressive exhaust presence both inside and outside the vehicle.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Best prison the Internet and quick order fulfillment. Glad to have found Autoplicity!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.

Not only did they have the best price, I promptly received the following e-mail message the next day after I ordered.<br><br>Hello brian willard!, <br>Good news!

Best prices I could find on bug shields and rain guards!
