i looking into get weiland mainfold some headers and a tune. would this hop me up a bit i hav a 04 ext, cab sierra 5.3L

First of all get a tune and go from there. Lots of other options...

Cold air intake, ported throttle body, headers, cat-back exhaust, cam, torque converter, electric fans, et.c

What you do next depends on what you have to spend...

well my 1st two steps were lt headers and a tune im lookin to put at least 12-1400 in motor work. alone this is just a truck truck lookin to kick a few buts when the time is there.

You'll notice a huge difference with the tune and the headers. If you're looking to spend another $1200 or so, go with a cam and torque converter.

If you have $1400 to spend, then do what Yankee said--Tune, CAI, LT's, ORY, Cam, ported TB, etc. If you know how to install that stuff yourself, you can save a lot of $$$!!!

do NOT buy a weind intake manifold...spend the cash on a stall, headers, tune and you'll be happy. I know I am!

The stock cats flow fine, your money is better spent elsewhere.

There are some different headers you can look at, I forget which ones will pass emissions. Look into Thorley, Pacesetters, etc.

skip the intake manifold for awhile...but get tune, headers, cam, stall, gears and hit the road
