Attached to the back of the catalytic converter, which is how it got its name, Jeep Wrangler YJ cat back systems can improve horsepower and thusly driving performance on difficult off-road trails. They do so by removing expended gas from the engine more expeditiously than a standard section of exhausts pipes. Because they are larger than stock parts and create less back pressure, they can expel these used gases in short order. Another attractive feature of the cat back system is that it contains a special muffler that produces a deeper, angrier sound or roar that most off-roading enthusiasts adore. We stock a nice selection of Jeep Wrangler YJ cat back systems and accessories.
