About Us

Welcome to the United Muffler website and our online catalog!

What We Do

We manufacture heavy duty mufflers, truck exhaust systems, and exhaust accessories. Our round truck mufflers range from 3″ to 16″ in diameter. Our oval truck mufflers come in 4 different sizes. We manufacture gas and diesel mufflers for school buses, construction equipment, industrial equipment, and custom mufflers for other vehicles needing heavy duty mufflers. From one muffler to pallet quantities, we have the right solution for you.

Other exhaust accessories available are flex tubing, Torca seal clamps, band claps, rain caps, mandrel bent elbows from 2″ to 6″ in aluminized or 304 stainless steel and many other installation accessories.

We were fortunate to have Ross Shuttleworth, “The Guru” of welded steel truck mufflers and Tony DaCosta (part owner) on our team. They spent several months setting up a “state of the art” heavy duty mufflers manufacturing facility. We are excited to provide you with mufflers you will be proud to show your customers.
