HEY that's 185hp to you mister It will have more hp by the end of the summer not much but some. Plan on buying headers, power chip, and will rebuild the engine and swap in a five speed from a parts Blazer. Do you guys think headers are worth it.

I have heard those 4.3's sound pretty fricken sweet with dual 40 series flowmasters

Don't forget to add CAI and throttle body spacer to your list. Both cheap and effective. Headers are well worth it if you can get them cheap, I'd check out ebay first.

I've had horrible, horrible experiences with eBay headers.

o.k so I think my cat has a slight rattle to it and it is driving me nuts. Can I just remove it or will it make my vehicle run bad because I have 200 o2 censors. Or should I get a high flow cat? Will it make it sound better? What is a CAI?

Hmm I've had the opposite. Had to relocate an o2 bung on the last set, but other than that they've all been good.

Cold Air Intake. The only thing your post cat O2's do is tell you if your cats are working. It won't have any affect on how it runs. No cats will give it more sound for sure. I took the O2's off my car when I did headers they are sitting in my tool box with caps on the bungs.
