In this article, we’ll explain what a catback exhaust system is, what it does, and why it’s different from your run-of-the-mill exhaust systems. There are seemingly endless available upgrades when looking to enhance vehicle performance. It certainly rings true when it comes to your vehicle’s exhaust system. One term that you’ve probably heard if you’re in the market for an aftermarket exhaust upgrades is cat-back exhaust. What exactly does it mean, and how does it change the way your vehicle performs? This 2009 Pontiac G8 GXP is one of approximately 1,830 examples produced, and it has 16k miles.
If you've got questions about cat-back exhaust systems, pipe diameters, muffler type, or anything else, talk with our product specialists. All 1995 model year vehicles, and all 1992 model year or earlier vehicles. All model year vehicles that were manufactured with EPA or Federal emissions certification. Exhaust gases from the cylinders are collected in the exhaust system to prevent harmful fumes from entering the vehicle.
One main reason for choosing to remain with a stock system is because it comes already installed on your vehicle. You should know the difference between a dual exhaust and a dual exit exhaust system. But it is easy to mistake a dual exit exhaust for a dual exhaust system. The materials are often 304 stainless steel or aluminized steel. The stainless steel is usually coated in special metals that make it corrosion-resistant. This means there will be a reduction in the amount of load on the engine, leading to higher mpg and fuel efficiency.
Or are you a more relaxed driver who takes the roads less travelled? Knowing your driving style will help you pick a cat back that not only sounds good but also performs well. Lastly, you need to decide what material you want your cat back to be made out of. If you're looking for a way to enhance your car's performance and style, a cat back exhaust may be the perfect solution. All 1993, 1994, 1996 and newer vehicles that were manufactured with California or 50-State emissions certification.
The DroneTrap system is wrapped up in our stamped multi-wall resonator that reinforces the housing inside and out. This high level of manufacturing protects the resonator from warping or splitting at the welds under exhaust movement.

The amount of horsepower gained from installing a cat-back exhaust system varies by vehicle and the system’s design. However, when combined with other performance enhancements, the gains can be more significant. The primary goal of a cat-back exhaust is to reduce back pressure, allowing your engine to breathe better and operate more efficiently. The factory exhausts come in mandrel bent tubes made of stainless steel or aluminized steel. Besides offering longer durability, the construction also ensures there’s free flow of gases. To improve this, you can opt to replace some parts of the exhaust system using aftermarket performance exhaust systems.
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
