Standard mufflers are wimpy. Toughen up your truck with a single or dual exhaust stack. Adding this key diesel truck accessory improves your ride’s power and sound. Savor the gains in torque and horsepower while enjoying the mellow rumble of your new smoker. Most of these truck add-ons don’t require welding and many install with simple hand tools. Some assemblies require a quick drill hole, but rolling with these flat black or mirror polished exhaust stacks of strength makes this minor alteration worth it. Whether you’ve got a Duramax, Cummins, or another diesel engine under the hood, we’ve got exhaust stack parts for you.
