Aftermarket exhaust systems are a great way to boost the performance and style of your ride. With the best systems capable of increasing engine power, improving fuel economy and even changing how your machine sounds. Since 1976, DG Performance has been producing high performance powersport exhaust systems, with a focus on street motorcycles, ATVs and dirt bikes. At Dennis Kirk, we have an unmatched selection of DG exhaust systems, parts and accessories to upgrade your ride.

DG became famous as an authority on dirt bike exhausts, and continues to produce innovative and reliable dirt bike exhaust systems. Choose from a variety of parts that will help you thrive on race tracks or outdoor trails, including bolt-on steel silencers, four-stroke mufflers, slip-on mufflers, swivel spring kits and exhaust inserts. DG has shifted their focus more towards street motorcycles and ATVs/UTVs in recent years, and produces many of the same full exhaust systems and parts for these machines.

In addition, we offer a number of other quality DG powersport parts and accessories. ATV riders can choose from various nerf bars, skid plates, front bumpers, grab bars and cooler racks to protect your ride and your beverages on rough trails. You can also squeeze even more power out of your dirt bike or snowmobile engine by keeping the fuel flowing with DG carburetor jets and carburetor kits.
