Stainless Works Smooth Tube Mufflers

5.0 out of 5 stars 2 Customer Reviews

Stainless Works smooth tube mufflers are some of the smallest, most compact models available. They offer a nice rumble at idle, and then quiet down as you gain speed. A reversible design lets you choose the sound level you want. Smooth tube replacement mufflers feature 304 stainless steel construction throughout—including the body, core, ends, and SS wool packing. Order the length and inlet/outlet diameters needed for your application.
