aFe Exhaust Systems
aFe designs and manufactures performance exhaust systems in Corona, California, for cars, trucks, SUVs, and diesel trucks. From aggressive cat-back and axle-back systems to high-clearance off-road setups, every aFe exhaust is engineered to improve exhaust flow and deliver a distinct sound for your vehicle. Explore our full lineup of exhaust systems, including configurations and components, below.
Exhaust Systems Built For Sound
aFe exhaust systems are designed with a sound-first mentality to deliver the right tone at idle, cruise, and wide-open throttle. We aim for deep, aggressive tones that make a statement without being obnoxious. We publish sound videos for our systems so you can make sure it’s the exact sound you’re looking for.
Stylish Exhaust Tips
A great-sounding exhaust should look just as good as it sounds. Every aFe exhaust system is built with clean, precision welds and exhaust tips that make a statement, lending a custom look. We offer clamp-on stainless steel tips in different finishes: Polished Steel, Black Powder-coated, Carbon Fiber, and Blue Flame.
Exhaust Systems Made in the USA
Every aFe exhaust system is fabricated in-house at our Corona, California facility, with expert mandrel tube bending and MIG and TIG welding. Through extensive engineering, R&D, and real-world driveability testing, our systems are designed with factory-style flanges and hangers, requiring no cutting for a seamless, bolt-on fit. All under one roof, from testing and manufacturing to Tech Support, “Made in the USA” means better quality control and the ability to help you every step of the way.

Types of Exhaust Systems & Components Offered
Not sure which exhaust system fits your goals? aFe offers cat-back, axle-back, high-clearance, and DPF-back configurations. Here’s a breakdown of each option, along with the components– like universal mufflers and exhaust tips– and special features– like electronically-controlled cut-out valves– that complete the build.
Exhaust System Configurations
Cat-Back
A cat-back exhaust system is the most popular exhaust upgrade, replacing everything from the catalytic converter back to the exhaust tip. Upgrading to a cat-back system improves exhaust flow, increases horsepower, and delivers a more aggressive exhaust note than your factory setup.
Axle-Back
An axle-back exhaust system runs from the muffler to the rear axle and out through the exhaust tip, leaving the catalytic converter and resonator untouched. Because they have fewer components, axle-back exhaust systems are generally more affordable than cat-back exhaust systems.
DPF-Back
A DPF-back exhaust system replaces the components from the diesel particulate filter (DPF) to the exhaust tip, leaving the DPF itself untouched. This diesel exhaust upgrade improves exhaust flow and gives your diesel truck a deeper, more powerful exhaust tone.
High-Clearance
For trucks and SUVs built for the trail, aFe offers off-road exhaust configurations engineered for maximum ground clearance, routing the exhaust to avoid obstacles without sacrificing performance. Explore aFe high-clearance off-road exhaust lines like the Hi-Tuck and Rock Basher.
Exhaust Components
Performance Mufflers
Our mufflers produce an aggressive sound during acceleration while maintaining a smooth exhaust note at idle. We implement a high-flow, straight-through design to improve performance and reduce droning. Available as part of a complete exhaust system or as universal mufflers.
Exhaust Valves
Many systems work with factory exhaust valves. Vehicles with factory exhaust modes retain the factory exhaust motor and electronics to actuate the exhaust valve.
For our Gemini XV Models, an electronically controlled valve is installed before the exhaust muffler to quickly switch between mild and aggressive with the push of a button on a supplied key fob.
Headers & Manifolds
Exhaust headers and manifolds replace the factory exhaust manifolds, which can be prone to failure. Headers are sound and performance-oriented, whereas exhaust manifold replacements offer superior reliability. Learn more about why you should ugprade.
Stainless Steel Exhaust Tips
Give your exhaust the perfect finishing touch. Customize the look of your exhaust with universal clamp-on stainless steel tips in a variety of different finishes– Black Powder Coated, Polished Steel, Blue Flame, or Carbon Fiber.
Mid-pipes, Y-pipes, Down-pipes
A Y-pipe merges two pipes into one, a mid-pipe connects the front and rear sections, and a down-pipe links the turbo or headers to the rest of the system. These components improve flow, reduce backpressure, and deliver a more aggressive exhaust tone.
Catalytic Converters
