Cat-Back & Axle-Back Exhaust

A performance exhaust changes how your truck or car sounds and lets it breathe easier. We carry bolt-on cat-back and axle-back systems from MagnaFlow, Flowmaster, Borla and more, each made for specific vehicles.

Cat-back vs. axle-back

Cat-back replaces everything behind the catalytic converter — pipes, muffler and tips — for the biggest change in sound and flow. Axle-back replaces only the muffler and tips behind the rear axle: less cost, easier install, mostly a sound change.

Sound level

Most systems come in more than one tone, from a mild touring sound to an aggressive one. Straight-through mufflers (MagnaFlow) give a smooth, deep tone; chambered mufflers (Flowmaster) give the classic muscle sound; Borla offers several levels per vehicle. The listing names the sound level.

How to get the right fit

Match year, make, model and engine — and for trucks the cab and bed length. Check the tip layout too: single or dual, side or rear exit.

Delivered to your door. We ship to all 48 contiguous states from US warehouses — most orders leave within 1–3 business days and arrive in 3–7 — with 30-day returns on unused items. Enter your vehicle at the top of the page and we'll show what fits.

Common questions

Will a cat-back exhaust set off a check-engine light?

Cat-back and axle-back systems bolt on behind the catalytic converter and don't touch the oxygen sensors, so they normally don't set a check-engine light.

Is it street legal?

These systems keep the factory catalytic converter in place. Local noise rules still apply, so pick a sound level that suits where you drive.

Can I install it myself?

Most bolt on with clamps or flanges using hand tools; the product details list what's included.
