Performance Exhaust Installation


Considering a performance exhaust system? Most car, truck, and SUV manufacturers leave a good amount of room for improvement when it comes to horsepower and torque. Vehicle manufacturers are subject to laws and regulations that require the cars, trucks, and SUVs they manufacture are compliant in every market they are sold in. Additionally, manufacturers have to factor in production costs that could drive up the sticker price of a new car and they need to design cars which are attractive to all potential customers. With some minor modifications to your stock vehicle parts you can boost engine performance gaining valuable horsepower and torque.

An aftermarket performance exhaust system is one of the first upgrades car enthusiasts turn to in order to free up some of the power in your motor. A performance exhaust will provide a fast and more efficient path for the exhaust gases to escape your engine. When you motor can breathe better, the engine control module is able to push more fuel and air into the combustion chamber which results in more power and responsiveness when you hit the gas pedal.

When considering an aftermarket performance exhaust system, one key feature to look for is mandrel bent tubing. There are two primary methods used when bending exhaust piping to fit your vehicle. The most common method used due to its lower costs is the “crush-bend” technique. The problem with this method is it creates crinkled areas in the pipe which not only decrease the diameter of the pipe but also produce possible restrictions in exhaust flow. This increases back pressure in the exhaust system which results in a reduction in power and fuel mileage. The second and more expensive method for bending exhaust piping to fit a vehicle is called “mandrel bending”. Mandrel bends are smooth so the pipe remains a consistent diameter throughout the exhaust system. Additionally, mandrel bent tubing eliminates potential exhaust flow restrictions from kinks and ripples in the piping.

Types of Aftermarket Exhaust Systems:
  • Axle-Back : Replaces the exhaust system from the rear axle to the muffler and has the least effect on performance and fuel economy.
  • Cat-Back : A cat-back exhaust system replaces the stock exhaust system from the catalytic converter back to the muffler, and has a moderate effect on fuel economy and engine performance.
  • Header-Back : A header-back exhaust replacement completely removes your stock components and replaces them with aftermarket options. This has the greatest impact on performance and fuel economy.
Benefits of a Performance Exhaust

Increased Engine Power

​The most popular reason car enthusiasts choose to invest in an aftermarket exhaust system is the increase in horsepower and torque it will provide. While a performance muffler exhaust system won’t deliver the same kind of power gains you’ll enjoy from a supercharger or turbocharger, it does have the potential to add several horsepower to you motor by reducing back pressure. While some back pressure in the exhaust system is necessary, too much can stifle the breathability of your engine which results in reduced performance. Typically, you can expect about a 10% increase in torque and horsepower from a performance exhaust installation.

Performance Sound

The second most popular reason car enthusiasts consider an aftermarket exhaust upgrade is the sweet sweet exhaust notes produced by a properly tuned exhaust. An aftermarket exhaust can vastly improve the sound and tone of your engine. Vehicle manufacturers go to great lengths to reduce the sound of a car, truck, or SUVs engine because the majority of car buyers prefer a quiet vehicle. Performance exhaust manufacturers on the other hand, take the opposite approach, they engineer their systems to let your motor purr as it was intended to. There’s something about being able to hear and feel the rumble of your motor than sends shivers of delight up the back of a true car enthusiasts.

Increased Fuel Economy

One of the last things you may be factoring into your performance exhaust buying decision is increased fuel economy. While it may seem counter intuitive, aftermarket exhaust systems do have an impact on the amount of fuel your engine will consume. While not huge, you can expect to enjoy a boost in fuel economy with your aftermarket exhaust system thanks to the reduction in back pressure in the exhaust system that helps your engine perform more efficiently. If you’re just going with an axle-back exhaust or muffler replacement, you won’t remove enough restriction to see much of a boost. However, a cat-back or full exhaust and header replacement will certainly boost your miles per gallon of fuel.
