Wow, that's a mark-up of 1.21! Any guesses on how much was exhaust versus EFI tinkering?

My exhaust is starting to give me the "feeling" of the beginning of it's downslide. I have the CA emmissions, so that means three cats. The two on the downpipes are dealer only at something like $300 each. My brain has been churning on what else can be done.

That same 1.21 on my 3.0L 24V would get ~214HP (not to the wheels of course).
