By freeing up the restrictions in the exhaust system, a cat back exhaust can help your engine to breathe more freely. This, in turn, can lead to a significant increase in horsepower. If you love cars just as much as we do, then you know that one of the best upgrades you can make to your vehicle is a cat back exhaust. But if you're not familiar with this term, don't worry – Vandemon Performance is here to break it down.

Whether it’s wowing people at a show or getting every advantage over the competition on the track, our exhaust systems will help your car perform its best. They are usually the last systems to get addressed by performance drivers, who put a majority of work into turbo systems or custom tunes.

From cat-back exhaust systems, emissions compliant catalytic converters, performance mufflers to custom exhaust parts, buy the automotive part your vehicle needs. In addition to boosting your horsepower, cat-back exhausts can make a massive difference to the sound of your car, especially if you choose exhaust tips designed for acoustics. Basically, catback exhaust systems upgrade regular exhausts, improving the flow of exhaust gases and the performance of your engine with wider pipes and smoother bends.

Most designs of the time therefore included secondary air injection, which injected air into the exhaust stream. This increased the available oxygen, allowing the catalyst to function as intended. Cat-back exhaust systems replace every component behind the catalytic converter, including most piping, mufflers, resonators, and tailpipes.

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
