Conclusion
There are a few different types of exhaust systems for the Subaru WRX. The most popular type is the cat-back exhaust system. This type of system replaces the stock muffler and exhaust piping from the catalytic converter back to the tailpipe.
This allows for a more free-flowing exhaust, which can increase power and improve fuel economy. A cat-back exhaust system will usually include a new muffler, new exhaust piping, and new tips. Some systems will also include a new catalytic converter.
Another type of exhaust system for the WRX is the header-back exhaust. This type of system replaces the stock headers and exhaust piping from the header flanges back to the tailpipe. This allows for an even more free-flowing exhaust, which can further increase power and improve fuel economy.
A header-back exhaust system will usually include new headers, new exhaust piping, and new tips. Some systems will also include a new catalytic converter.
