Premium Exhaust Systems for Maximum Performance

From mild to wild, direct fit to completely custom, and everything in between, the Holley family of exhaust brands has products to increase horsepower, improve performance, and get your ride sounding the way you want it to!

Exhaust Systems - We produce a variety of axle-back, cat-back, and header-back exhaust systems that are direct-fit for a wide range of vehicles including muscle cars, trucks, SUVs, imports, European cars, and much more. These systems feature high-quality materials, mandrel bends, and a variety of muffler options that will provide instant power increases and the sound that's just right for your car.

Headers and Exhaust Manifolds - To maximize performance, replace your restrictive OEM exhaust manifolds with a high-flowing aftermarket manifold or header system. Our headers and manifolds provide huge horsepower increases while also cleaning up the aesthetics of your engine bay.

Mufflers - Whether you're building a completely custom exhaust system for your classic muscle car or swapping in a set of mufflers on your late-model truck to give it an aggressive sound that matches its looks, our wide range of mufflers is sure to have something to get your hot rod sounding the way you want it to.

Catalytic Converters - Flowmaster Catalytic Converters are designed to fit and function properly on a large variety of vehicles, and all our Direct-Fit Federal Catalytic Converters are designed to meet or exceed both OE and USEPA standards. Their stainless steel outer shell and heat shield provide long-term durability, while OEM-grade substrates carry the noble metals and meet or exceed all OEM and 49 State USEPA emissions standards.

Exhaust Tips - We all want an exhaust system that makes good power and sounds great, but we also want it to look great. Our vast selection of exhaust tips includes sizes and designs to that ensure your car or truck exhaust will end on a high note.

Builder Components - If you're going the custom route, we have everything you need, from flanges to tips, so you can construct a one-off masterpiece. These components are available in various sizes and materials to fit any job or budget.

X/H/Y-Pipes - Dyno-proven power producers but sometimes forgotten, crossover pipes are superior performers compared to true dual exhaust systems and offer a more refined exhaust note. We offer direct bolt-on kits for many cars as well as universal crossovers that can be integrated into OEM style and custom exhaust systems.

Cutout and Multi-Mode Kits - If your daily driver doubles as your weekend warrior or your date night ride needs to hit the track tomorrow morning, our cutouts and multi-mode kits will free up some horses and properly announce your arrival.
