The Difference Between Cat-Back & Axle-Back Exhausts

A car exhaust system starts with the noticeable exhaust pipes. Under the car are the exhaust tips. The muffler is next, and pipes separate it from the curved catalytic converter. The other curved component going in the opposite direction is the exhaust manifold. The difference between cat-back & axle-back exhausts affects the sections that need an upgrade or replacement. Cat-backs replace the pipes, tips, muffler, and the pipes leading to the catalytic converter. Axle-backs replace the tips and muffler. Both provide a better car crank sound and driving performance.

When you buy the Cat-Back Valvetronic Maxflo Exhaust System, you get a valved, emissions-legal plug-and-play system with more power, better appearance, and control over car sound. It has CNC mandrel-bent 14-16 gauge T304L stainless steel construction, and U.K. imported aerospace-quality Helical Limited exhaust valves.

At Fab Speed, we deliver top-quality service and products tailored specifically to your vehicle. That’s why the valved Porsche Macan rear slip-on exhaust (2018–2022) isn’t compatible with the Porsche 992, they're designed for different models. To get the right fit, order the exhaust system built for the Porsche 992 Twin Turbo or Twin Turbo S.
