Patriot Exhaust Mufflers

Product images may differ from actual product appearance.

Smithy's Mufflers
The world's oldest performance muffler is now 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 construction and 3-1/2" hammertone finished cases assure the original Smithy look.

Street Rod Stainless Mufflers
Perfect for the ultimate street rod, our 304 polished stainless steel glasspack muffler features our six sided louvered core for improved noise absorption. Only long strand sound absorption material is used for increased service life.

Hi-Flo Glasspack Mufflers
Heavy steel core design has six rows of louvers for reduced restriction and better sound absorption. Long strand sound absorption material is used for increased muffler life. Hi-Flo Oval mufflers are great where ground or axle clearance is limited. Hi-Flo Header Mount mufflers accommodate most 3-bolt header flanges.

Universal Mini Muffler
Reduce exhaust noise without a bulky exhaust system. Simple ''screw in place'' installation makes this muffler incredibly versatile.

Two Stroke Silencer
Tone down the exhaust note of your 2-cycle engine. Simple ''slip in'' design allows this silencer to fit most expansion chambers.
