Texas Speed and performance headers?
 

I am in the market for a set of headers for my 2003 h2

I came across Texas Speed and Performance and they have a set for $370 for all trucks 99-2007. I called them and asked if this applies for a 2003 Hummer H2. They said they havent fitted them on an H2 but will probably fit.

Has anyone else tried these or know of anyone who has?

heres a link to their page for the headers
Texas Speed & Performance 1-3/4" Stainless Steel 1999-2007 Truck Headers

I moved this from where you posted it in the ARCHIVE ONLY Drivetrain Are, where it says: "This section is an archive of older posts, please post new questions in the specific model section. Thank you!"

Thanks... i should have payed more attention to that.

The long headers will require you to modify your exhaust. the shortys are a direct fit. Mine is a california vehicle so I have to have cali legal headers in order to register it. I went with these 2003 HUMMER H2 JBA Headers Cat4ward Headers 1850S-3JT - SummitRacing.com for a couple reasons. 1. to keep it smog legal. 2. because the ceramic coating will remove most of the ambient heat from your exhaust out of the engine compartment.3. they are a direct fit. (no exhaust mods needed.)

My guy installed them in about 30 minutes and it went to the smog shop (after changing an 02 sensor and driving for fifty miles) and passed with no issues.

Thanks for the info.
I plan to modify my exhaust system so long tubes will not be an issue for me. I am from michigan and do not have to worry about smog fortunatly...

Did the headers make a change at all in performance

Well the first thing I noticed was that it sounded a little throatier. Also have a little more bottom end before the blower kicks in. Seems like the engine isnt working very hard when I'm at cruising speeds.

Might have to replace the stock muffler though . I'd like it a little louder.
