Cat Back Exhaust Systems

The Cat-Back Exhaust Systems collection at Revline features aftermarket exhaust upgrades designed to improve sound, power, and efficiency. A cat-back system replaces the factory piping from the catalytic converter back, unlocking a deeper exhaust tone, reduced backpressure, and proven horsepower gains. Available in stainless steel and titanium options, our catalog includes single-exit, dual-exit, and valved systems for popular platforms like Subaru WRX/STI, Toyota Supra, Nissan 350Z/370Z, BMW M-series, Ford Mustang, and more. At Revline, we carry cat-back exhaust systems from trusted brands like Valvetronic Designs, AWE Tuning, Tomei, and aFe Power so you can customize your build with confidence.
