Understanding what cat-back and axle-back mean is vital in order to properly decide what works best for you. A cat-back exhaust system replaces all of the exhaust system components from the catalytic converter back. An axle-back exhaust system replaces all of the components from the rear-axle back. Axle-back exhausts tend to be a bit cheaper than cat-backs, but cat-backs will also give you more performance and a richer sound. In the end, it comes down to what you're looking for in an exhaust system. Both cat-back and axle-back have their pros and cons.

If you'd rather not upgrade the entire system and just want to do specific mods, that's also a great option. Swapping out your factory muffler for an aftermarket one is a great way to completely change the sound of your exhaust while also freeing up some horsepower. Aftermarket exhaust tips add a bit of flair to the rear end of your ride.
