Can CAT's actually help instead of hurt? Dyno Results inside

I would like to see the results on a the same motor without boost. It's hard to say. Backpressure is a funny thing sometimes.

interesting.. I would have thought it would hurt power on a blown car. that was a good post though.

I would of also liked to see results on a N/A motor. I also thought it would of hurt HP more than just 2HP, but the TQ increase amount across the band is what surprised me. 20ftlbs more at 2500rpm. thats pretty impressive and no less than +10 at 6k.

I know the BP on my system is very low for having 2 HF cat's on it.
i'm sure it surprised quite a few people
