Mazda CP-E CX-7 QuickPower Pipe
The exhaust system for the CX-7 comes in two pieces: The QuickPower pipe and the rear muffler section. Both are modular, so they can be mixed and matched with stock exhaust components. The QuickPower pipe is essentially a test pipe on steroids. It replaces the second catalytic converter on the vehicle, and runs from the downpipe back to the muffler section. If you are looking to improve power over stock but keep the sound the same, opt for this piece. The rear muffler section bolts to the end of the QuickPower pipe, and can be mated to the stock CX-7 exhaust. So if you are looking for great sound, but are not so concerned with big power gains, opt for this piece. Finally, for the greatest performance and sound increase, choose both the QuickPower pipe and the muffler section!
