I know he is talking about the varioram. But seriously, can you get 300hp out of a 993 just by adding the fabspeed airbox and their supercup's exhaust. Or does doing this give you the feeling of 15 extra HP. I was also looking at their headers but they do not give the HP gain. Also, are headers legal for D Class club racing, or can you only bolt on mufflers.

I havent done the header thing, but the stock exchangers aren't equal length tubes and that is a key to proper flow. Now is it eccential on a 993 ??? Don't know.

Not to thread hijack, but what is the consensus on cat bypasses? They lower torque but free up HP which is better for a track car, yes? Chris, what are your thoughts and have you dyno tested your units? Sorry if I missed a thread on it.
