Product Details

The Flowmaster 40 Series Chambered Muffler delivers an aggressive exhaust tone that's perfect for enthusiasts seeking a bold sound both inside and outside the vehicle. This performance muffler features Flowmaster's signature two-chamber design that produces a deep, throaty rumble while maintaining excellent exhaust flow characteristics.

Key Features:

  • Aggressive exterior exhaust tone with noticeable interior resonance for that classic muscle car sound
  • Two-chamber Delta Flow technology for improved performance and maximum sound control
  • Constructed from fully welded 16-gauge aluminized steel for exceptional durability and corrosion resistance
  • Versatile design ideal for street/strip performance and off-road applications
  • Direct-fit chambered design requires no packing or internal baffles to wear out or blow out

The 40 Series is Flowmaster's most aggressive sounding muffler, making it the go-to choice for muscle cars, hot rods, and performance trucks. The welded construction ensures long-lasting performance, while the chambered technology delivers the distinctive Flowmaster sound that turns heads wherever you go.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

This was my first experience ordering from Autoplicity. The ordering process was easy, I got the parts that I wanted at the best price I could find, and they came quickly. I can't ask for more than that.

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!!
