Patriot Exhaust has several style mufflers to adjust the sound of your ride. From the classic Smithy's® to a Varaflow® Tunable Muffler we offer many different styles to best suit your needs.

Smithy's® Mufflers

Smithy's Mufflers

The world's oldest performance muffler is available for that "resto-rod" or your 1950's custom. Get the muffler your dad used to impress his friends, and yes, it's still guaranteed not to blow out or leak. Double end cap constructions and 3 1/2" hammertone finished cases assure the original Smithy look.

Varaflow® Tunable Muffler

This new muffler features SFI Technology and utilizes an electric motor and valve assembly which allows the user to adjust the sound of their exhaust, while they drive! Tune out annoying drones when driving down the highway and then turn it up to make more noise on “Cruise Night.” Idle difference between open and closed is 5 dB and at 5000 RPM the difference is closer to 15 dB. For every 10 dB increase sound is twice as loud.


At Patriot Exhaust we offer several classic header and exhaust styles. Ranging from Lakester style headers for the Bonneville and Dry Lakes look to Fenderwell headers for the gasser look. Take your time and find the look you desire for your hot rod.

Lakester Headers and Pipes

Lakester Headers

Give your rod a nostalgic look with a Lakester style header. Our classic Lakester design allows for hookup to an under chassis exhaust system, but by removing the provided block-off plates you can easily uncork your headers. The traditional Lakester headers capture the look and performance reminiscent of the Bonneville and Dry Lakes racers. Traditional Lakester headers are designed for use with no other exhaust system for that open header style and sound. However, if you prefer to tune down the noise we have muffler inserts available to mild the sound.

Side Exhaust

Patriot Exhaust offers several styles of side exhaust to give your hotrod a racier custom look. Our Shielded Side Pipe offers a large inlet and outlet with a low back pressure six-sided louvered core mufflers to guarantee performance and create that distinctive power tone.

The Lake Pipe “4” gives you the look of an expensive tuned header side pipe at a fraction of the cost. We also provide Side Tube Turnouts.
