[Captain of the Titanic]

I have not yet put on my K&N cold air system. I can't decide if I should. I read all the stuff about it doing nothing, etc. But I hear positive things as well.

I had a 99 tahoe before the Hummer(s) and ran headers/dual cats/dual exhaust as well as the K&N Setup. It gave me more power but also gave me a 4 MPG increase. I understand that headers on my Hummer are a "nothing" mod as well. I was VERY happy with the mods.

I look at the stock exhaust, and it doesn't look tuned to me, so why wouldn't the Headers help? I plan on doing a true dual exhaust, will it help?

I know the Hummer is detuned from the Escalade as well.

I also hear that if we do up the HP, things will break...

I am currently running a Jet stage one preprocessor with excellent results (better throttle response and 1/2 MPG better for 3000 miles, so far)

Sigh.. I am so confused.... I've got the headers (Hedman) and K&N in the garage... Should I put them on???

Please give me your opinion both ways. I have to make the decision one all this soon.

Thanks guys (and gals) for the assistance
