Header for 2006 H3 w/3.5L 5 cyl
I have a 2006 H3 and considering putting a header on to compliment the high performance chip, new air intake system and magnaflow dual exhaust I am having installed. I'm considering having a header installed but have some questions I would appreciate getting some feedback on.
The header requires the catalytic converter be removed from the system. So the air sensor behind the converter will be gone. A GM mechanic told me that the "check engine" light will come on and stay on and there is no way to fool it. So sounds like my only option is to let is stay on and burn out. Any advice there?
The header I am considering is almost $900. Is there enough performance enhancement to justify a $900 investment? It's a Hummer, so of course I am not looking for speed! But I would like to have more low end tork and better accelerator response. My H3 has a factory 456 differential.
Really appreciate any advice you can give me. Especially if you have personal experience with a header on the 3.5 5 cyl.
Thanks all!

The chip is not as good as a PCM tune, I would look at PCM of NC or a local guy. The 06 only has one O2 sensor so it is the easiest H3 to put a header on with no codes. Most all H3 headers have at least ONE hole for the sensor. Expect about 30 hp from the header. Look into a ported throttle body for better response too.

Spend your $900 on the proven reliable performance boost package: an Intake; PCM Tune, Efan Conversion, Port Polished TB, and Cat back exhaust.
If your exhaust manifold cracks, then do the header.

this is the route I went. all together these make a very big difference

I do drive alittle fast, but the biggest reason for my mods are to be able to drive down the highway at speed without impeding traffic
