Product Details

The Flowmaster Series Chambered Muffler is a performance exhaust muffler (also called a chambered performance muffler) built to give your vehicle a deep, aggressive exhaust tone and better exhaust flow than a stock muffler. Flowmaster is known for its chambered muffler designs, and this product line carries that sound and performance approach across all of its variants.

Key Features:

  • Chambered internal design that tunes exhaust pulses to produce a deep, muscular tone
  • Designed to reduce restriction compared with many factory mufflers
  • Durable steel construction made for long-term use
  • Available in multiple configurations to suit different exhaust setups
  • Straightforward bolt-in or weld-in installation, depending on the configuration

Whether you are upgrading a daily driver, a truck, or a muscle car, the Flowmaster Series Chambered Muffler gives you a classic exhaust sound with the build quality Flowmaster is known for. Select the variant that matches your exhaust configuration.

Great price!!

smooth transaction, Thank you.

Haven't installed yet. The ordering process and delivery time was exceptional Many thanks!

Website was relatively easy and the delivery time was great.

Great price fast cheap shipping

so far so good

Ordered a battery. Price was good, paid for upgraded shipping, which was a waste. Battery arrived ok, but packaging was not dense and secure, especially given that this was a very heavy item.
