Enhance Sound and Flow with Axle Back and Cat Back Exhaust Systems
Improve your vehicle's performance, tone, and overall driving experience with axle back and cat back exhaust systems designed for direct fit upgrades. These systems offer a perfect blend of aggressive sound and enhanced exhaust flow without requiring major modifications, making them ideal for street driven vehicles and light performance builds.

Our axle back and cat back kits are available in stainless or aluminized steel, featuring mandrel bent tubing, tuned mufflers, and polished or black tips for a clean finish. Axle back systems replace everything from the rear axle to the exhaust tip, while cat back systems extend from the catalytic converter back. Both provide measurable performance gains and a noticeable exhaust note, all while maintaining emissions compliance.

Whether you're chasing a deeper sound, better flow, or a refined appearance, these exhaust systems deliver noticeable improvements with bolt on simplicity. Explore fitments tailored to your vehicle and driving goals.

Frequently Asked Questions

An axle-back system replaces the exhaust components near and behind the rear axle, while a cat-back system replaces a larger portion of the exhaust farther forward from the catalytic-converter area. Because a cat-back changes more pipe and usually more components, it can create a larger change in sound and flow. The exact layout still depends on the vehicle, so compare the included sections for the specific kit.

Choose an axle-back when the upstream exhaust is in good shape and your main goal is to change the rear section, sound, or tips with a smaller installation. Choose a cat-back when you want a more complete downstream system or the intermediate pipes and muffler section also need replacement. Vehicle-specific availability and the manufacturer design should guide the final choice.

Most performance cat-back systems change the exhaust note, but the amount and character vary widely by muffler design, pipe size, engine, resonators, and whether the vehicle has forced induction. Use the manufacturer sound level or sound description for the exact application as a comparison tool. Do not assume a larger pipe or larger tip automatically means a louder system.

Many vehicle-specific kits include the main pipes, muffler sections, clamps, and tips needed for the intended installation, but contents vary. Check whether the kit reuses factory hangers, gaskets, or hardware and inspect those pieces before starting. If the factory connection is heavily rusted, having replacement clamps, gaskets, or hardware ready can prevent a second order.

Most downstream exhaust changes are sold for use without mandatory tuning, but requirements can vary by vehicle and system. Check the manufacturer instructions for the exact part, especially if the exhaust is being combined with headers, intake changes, forced induction, or other performance modifications. Do not treat the requirement for one application as a rule for every vehicle.
