Yes those are the 2 pipes I have, and a werks 2057. I really just don't want to have to fork out another 100$ on a pipe and manifold. The only decent engines I have ran so far are the werks B5 and B6, and I would like to try out a P5 since the price dropped so low. I haven't really had much luck witht he werks lasting very long, but that may be due to user error in tuning more then the engine.
