In the exhaust system, a test pipe takes the role of the catalytic converter. It is possible to increase horsepower and a louder exhaust tone by switching to a test pipe. If you want a little more oomph, this could be an excellent route to go.
The word “test pipe” refers to a pipe utilized to determine whether or not you have a problem with your catalytic converter. Because of the greater exhaust flow, louder noise, and potential for additional power, some owners choose to leave their test pipes on all the time. Catalytic converter-related difficulties were the initial use case for test pipes.
To help you choose the best test pipes for your Subaru BRZ and Scion FRS, we compiled these five best test pipes for you!
