Cat-Back Exhaust System
An aftermarket exhaust which replaces all tubing and mufflers after the catalytic converter. A cat-back exhaust will generally provide the highest power increase when used with headers and a high-flow catalytic converter, although they will still provide a noticeable improvement over the stock exhaust. Depending on the design of the factory exhaust, an aftermarket cat-back exhaust may be bolt-on, clamp-on, or weld-on.
"Ever since I got my cat-back exhaust, my neighbors run after me and pump their fists when I leave for work at 5 in the morning. I must be doing something right if they’re cheering me on!"
