In the world of off-road driving, there are many oddly-named parts and accessories that make newcomers scratch their proverbial heads. But none of them are more perplexing than the Cat-Back system. No, the part doesn’t look or even sound like a cat. It is called-cat back because it is connected to the back of the catalytic converter, and because catalytic back system doesn’t sound quite as cool! So, they shortened it! The part is a popular aftermarket accessory that is considered an essential addition by most off-roading enthusiasts. The benefits of Jeep Wrangler TJ cat back systems are as obvious as they are irrefutable. A Cat-Back system removes spent gases from your combustion chamber faster than regular stock parts, which can improve horsepower, torque, and fuel efficiency. The part also adds an angry growl that most offroaders adore.
