cat or no cat?

[crazytrain65]

I will be installing headers this week and wonder if it is beneficial to remove my cat. i have a high flow one right now, with my codes deleted. Does it run better or will it just hurt performance?

Thanks!

Re: cat or no cat?

I have no cat, performance did not seem to suffer. I imagine no cat is better than hi-flow, but I am not sure. BUT if you have to pass emissions then stick with the high flow.

Minimal difference between hi-flow and no cat. It's up to you really, barring local laws.

well i have no emmissions testing in illinois.... and the code is removed, so no SES light. ill prolly juss cut it off. I just wanted a few opinions to make sure i wasnt doing wrong by removing it.

I first had high flow then gutted cat. Finally straight piped it and I like it alot better.
