All are capable of delivering a race-inspired exhaust note along with more power and torque. And this is why cat-back exhaust systems are considered to be one of the best performance modifications that are rewarding in power and sound and are highly effective for all driving purposes. Aside from maximizing your sound gains, the RSC® technology in every CORSA high-performance exhaust allows for a completely free-flowing air path to optimize your performance with every drive.
By running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, cat back exhaust systems improve exhaust gas flow, providing small performance boosts. However, your performance gains may be limited if your catalytic converter restricts gas flow, as a catback exhaust system is installed ‘downstream’ of the converter. Header-back systems are increasingly rare, namely because of modern emissions systems. Since removing your vehicle’s factory emissions components is highly illegal, the previous two options are more common. However, header-back systems are still available for some older, pre-emissions applications. In these cases, header-back systems offer more performance and volume than cat-back or axle-back systems
