About Our Semi Truck Mufflers


Cruising down the road, those shiny exhaust stacks can make your rig stand out. Their sleek look hides an imperative function to keep your truck running smoothly. They alone aren’t the only part that makes a difference to performance. Semi truck mufflers are an essential element to reduce exhaust noise and boost efficiency. 

If your truck is starting to get louder, it may be time for a new muffler. Other signs of a faulty muffler may include decreased fuel economy and increased odors. Whether its time to replace or you simply want to upgrade, we have an array of stock to help you find just what you need. Like other accessories, mufflers can also look while they work.

A Part for Every Truck

For those who seek high performance, a semi truck high flow muffler can help reduce fuel consumption, making each trip more efficient. Need to match your flashy stacks? A chrome muffler provides heavy duty protection with style. We also have stainless steel parts designed for minimal back pressure drop. 

Is your straight pipe unruly? We have performance stacks that not only dampen harsh sounds but also provide improved response and can boost horsepower. Under-cab mufflers are also available to help you get the best out of your rig, as well as steel inlet/outlet styles in array of sizes. Our quality mufflers fits most engine exhaust systems and are designed to last.

Other Accessories

For those trucks that pack an extra bang, we offer an array of resonators to help control the noise. Many offer a reduction of 3 to 6 decibels if added before installing the muffler. Most are made of durable steel that resists rust and come in different sizes.

When talking about semi truck exhaust systems, it can be too easy to just think about stacks. That, however, is only one part of your truck's exhaust. At Iowa80.com, we carry a vast collection of various exhaust parts and accessories, which includes Mufflers. Built to the highest quality standards, we support each and every exhaust part we deliver.
