I had never heard of it. When I looked it up, it looks similar to the OBX system (only in black) ...

I agree. Looks just like OBX except in black.
I tested OBX system, with a help from another WAZOO member, about 2 years ago. Hooked up a pressure gauge to O2 bung and drove with 94 factory system followed by OBX. At 2000 RPM, factory system registered 1.4 psi and OBX registered 1.0 psi. Sound wise, more deep mellow sound as opposed to more raspy sound from Corsa.
I have been running OBX for about 2 years and have no complaint.
I recommend using Torca clamps. Clamps supplied with the OBX were not very good - bolts sheered off while torquing.

The words "Maximum Performance" describing 2 1/2" pipe is a contradiction.
That size pipe cannot flow as much air as a 3" system.
