What are the benefits of a cat back exhaust?
The cat-back system frees the restriction of gases, reducing the engine’s work load and improving gas mileage. The free flowing gases flow unrestricted and the engine is able to produce more horsepower and torque as it is easier to push the gases through the exhaust.
Is a cat back exhaust loud?
The Catback systems start at the catalytic converter and include mufflers and exhaust tips. … It does include less restrictive mufflers and larger exhaust tips. This gives you a louder exhaust and, sometimes, a little power gain at the top end of acceleration.
