I have a 2001 sierra 5.3L. I get the impression that longtubes are better than shorts...is this true?

anyway, could you guys throw out some brand names that you like best and give the most power? I appreciate it

 

As far as long tube, Yes they are better. I have the pacesetters like alot of the others here. They are the cheapest so far. Hooker just came out with a set also but I am not sure on the price, but there are ASM,TOG, THROLEYS, and a few more aswell. They all sell for alot more then the pacesetters as far as I know. Right now I'd say go with the pace.. best bang for the buck.. Power wise I would say they all are pretty close as to the gains you will get..

 

Who the hell makes a set of good headers for a Z71 4x4?

 

What year? I just ordered a set of StainlessWorks for my 99 that I should be installing some time next month, and I'll be reporting back to SW on the fitment. They plan to make them EGR compatable too. As it is now, they know that their system will fit 03-05, and hopefully I'll be able to report good news for us 99-02 guys.

Their headers are available as just headers, headers with off road y-pipe, and headers with a catted y-pipe. They come with a 2.5" collector, but they'll put just about any size collector on them that you want...grippy had a set custom made with 3" collectors that he just had coated...they look sweet.

 

I got a 2003 GMC Z71 5.3 w/ egr & A.I.R......by the way BudHayes....is it cool if I add you to my Friends list?

 

Wow, I didn't know that that 03's came with EGR and AIR, I thought that 01 was the last year for that

...sure man, that's cool

Alright man...thanx for that! Actually.....the A.I.R. pump is non-existant on the 2003 but the EGR is, and everything I read only lists headers for EGR w/ A.I.R......know anything about that?

 

[QUOTE=Torque_Wrench]That's news to me...I know that the ASM's and Dyantech's have an EGR provision, and they fit 99-05 4x4's. The SW's will have EGR soon enough though. If the headers come with a provision for EGR and the vehicle doesn't have it, it's as simple as blocking off the EGR port with a little plate. When it's the other way around there's a problem (if you have EGR and the headers are not equipped). Although, deleting EGR is simple to do with the proper tuning software and a plug for the pass side of the intake.

 

[QUOTE=budhayes3]Hey BudHayes....when you put your SW Headers on.....you wanna' sell your Gibson Shorties?

 

[QUOTE=Torque_Wrench]I already promised them to treyZ28, but first I'm sending the pass side one to SW so they can check and measure for the EGR port for future customers with EGR. If trey hooks up with something else by then, no problem...sorry about that.
