Does anyone have feedback on an independent dyno comparison on a 997.2 for sharkwerks (or Billy Boat) and/or fabspeed x pipe? Pre/ post install...

Trying to decide which one to pair with the fisters I just ordered. Both sharkwerks and fabspeed are claiming somewhat similar tq/hp gains over stock. TIA

Unfortunately, neither is likely true.... (I've got Fister + SW).
I think it's likely all sound, but I like telling myself that my car is now "Somewhere between 385 and 400 hp".

We have experimented in the past with the standard crossover design, and in our early beginnings as a company we also sold crossover pipes. After much R&D work and product development, we now offer an X-Pipe design as it has consistently shown stronger performance gains by utilizing a scavenging effect. This also allows both banks of exhaust flow to merge in the "talk zone" of the X, and provides a smoother, more refined exhaust note than crossover pipes, while of course being more aggressive than factory. We have found this to better match the expectation of sound from these Porsches.

Here is an explanation of the X-Pipe design and how it works.


If anyone is interested or has any questions, feel free to give me a call, email, or PM any time
