The Purpose Of A High Performance Exhaust System
When modifying your vehicle, adding a new high performance exhaust system is considered the best place to begin. Most of these systems are designed to perfectly fit your vehicle without any necessary modifications, unless otherwise specified by the manufacturer. The most common performance exhaust system available on the market is the cat back. Cat back exhausts are best described as the section of an exhaust system that links up all the way through the system from the last catalytic converter to the end of the pipe to the very tip. Another system of interest would be the axle back system, which simply replaces the muffler and the section of piping that connects the muffler with the remainder of the exhaust system. Other items you may be interested in upgrading include down pipes, a catalytic converter and a new header.
The entire purpose of modifying your car’s exhaust system is to reduce the overall amount of backflow pressure on the engine, giving it more room to breathe essentially. Most performance exhaust system manufacturers will implement a larger diameter of piping, along with higher-grade mandrel bent tubing, allowing for a much less restrictive flow in the entire system. The horsepower gains from installing this type of system depend entirely on the design of your current factory exhaust system, and the quality of the catalytic converters that are in-front of it. Your average stock converter will be very restrictive, and will offer less power gains from a cat back exhaust system. In that case it would be advisable to include the addition of a new high performance or racing catalytic converter in order to get the most out of the cat back system. When looking for new exhausts, always stick with the most time-tested, reliable manufacturers; it will pay off in the end.
