Hi guys, I'm looking to upgrade my exhaust. I've decided that I want to get the CP-E Austenite cat back, but I'm unsure what test pipe/high flow cat I want to run, and whether or not I want to get a new down pipe. I found a rather cheap pipe w/ hfc for $260(TurboXS-evox-cp) whereas the CP-E QuickPower pipe w/ hfc is $375. Basically I wanted to see if anyone knew if the TurboXS pipe would work with the CP-E cat back(i.e. Bolt-on), especially since it was designed to fit the Evo.
