After installing my FI CBE, I felt an additional bump in power and will be going on the same dyno to see what I gained soon.
I know Cats are the main restriction in the exhaust, that is why I don't think High-flow cats help too much. Its the removal of cats that makes power. Saying "high-flow" cat to me is like saying "fast snail"... I think its has more of a placebo affect on power.
