We get this question quite often. Will my car go faster if I upgrade the exhaust? Most of the time it will. Increased airflow from the engine will allow the engine to breathe and perform more efficiently. This is the same reason one would add a turbo charger to their engine. Increased airflow will always increase the horsepower and performance of the engine. An engine needs air to ignite the fuel which in turn propels the engine’s pistons. The more air you introduce to the engine’s ignition, the faster it will burn fuel and in turn the faster the engine will ignite and propel the vehicle. For example, we have dyno-tested certain vehicles before and after our exhaust installations to see just how much better they performed after the upgrade. Below you can see the dyno results from our CATBACK-370Z exhaust upgrade. The green shows the factory exhaust HP rating, and the blue shows the Top Speed Pro-1 Catback Exhaust upgrade rating. This customer gained 17 max horsepower and 11 ft-lbs of torque just by upgrading his exhaust! This is just one example, but it is a good indication of what aftermarket exhaust can do for your vehicle.

Keep in mind that this is a “catback” system which means we replaced everything back from the catalytic converters. If you want to increase performance, you will get the best results by replacing the whole system behind the catalytic converters with larger diameter high-flow pipes. An “axle back” system means it pertains to the exhaust system from the rear axle back. This will also improve performance and sound, but for maximum performance improvements, a catback system is the better choice. However, in some cases an “axle back” system is the only option. For example, most mid-engine and rear-engine vehicles have much shorter exhaust system because of where the engine is located. This also allows for more immediate access to the exhaust system, and less distance for the exhaust to travel making an exhaust Also, replacing just the mufflers or the exhaust tips will not increase your airflow, which in turn will not increase performance. In some cases, it may even restrict airflow even more therefore decreasing performance overall. Some drivers delete the catalytic converter altogether with what is called a “straight pipe” or “test pipe” to remove all exhaust flow restrictions. However, it is illegal to delete the catalytic converters with straight pipes in most parts of the world because of emissions standards violations. Also, it is important to consider the rest of the components in your vehicle from the engine to the drive shaft to the suspension. All of the components need to be built to handle this increased performance so by no means do we recommend upgrading your car without first making sure your car can handle any engine modification or upgrade. It is always best to talk with a professional mechanic who has experience in performance upgrades before modifying your vehicle.
