GMC Mufflers

Car mufflers and truck mufflers are often different. Many cars, but not all, have mufflers that are right at the tail of the exhaust system. For these, the muffler tip is a part of the actual muffler. When shopping through our muffler selection, keep that in mind, as most mufflers are actually listed as universal mufflers. Some of the most popular GMC mufflers are Flowmaster mufflers and Magnaflow mufflers. If you have any questions about mufflers for your car or truck, or if you are having trouble finding any GMC muffler on our website, please contact us.

Q: What is a muffler? Are there different types of mufflers?
A: According to our resident expert Deryl Atanasu, Mufflers are positioned by the manufacturer where there is space on the car. All mufflers tend to be placed behind the rear axle, as this allows a lower floor-pan in the passenger compartment. Vehicles with single exaust generally have the muffler placed in a direct line with the tailpipe and just before the exaust tip. Some high-performance vehicles have a dual exaust (i.e. corvettes), where both left and right sides have a muffler in a direct line with the tailpipe and just before the exaust tip. Other vehicles (i.e. camaro, firebird) have a single exaust pipe going back just past the rear axle. It then enters a muffler that is mounted in a side to side position. From there two tailpipes exit the muffler and extend to the rear or out the side of the vehicle behind the rear axle.
