Catalytic Converter power loss?
I had to put a Cat on my exhaust yesterday so the it would pass inspection here in Missouri. It's a 3" universal hi flo and I was wondering how much HP am I losing?
Thanks

That's what I was hoping to hear. It muffled the sound a little, but not too much. I put it about 16" behind the ORY. I was thinking of taking it back off and clamping a 3" straight pipe, but not sure if it's worth the hassle now.

Question, why would 2 Cats per each bank be better than 1? That's something I've been trying to figure out since the '96 Z28's came with 2 and claimed more HP.
