Hey guys where can i find some long tube headers for a 2004 5.3L Z71 4x4??? like a website not a company thanks

 

Dynatech makes headers for those vehicles. You can find them at a few of the sponsors on the right

do a search pacesetter is now making them for 4x4

 

StainlessWorks makes em: http://www.stainlessworks.net/cart/index.php

 

about how much hp can i get out of long tubes?

 

thorleys tri-y for only 440!!!

 

i am looking for longtubes for an 04 z71 as well.i've heard that pacesetter is making them but i can't find anything about them on their website

 

Another vote for Dynatech. Their Customer Service was excellent. Not sure why but in my 4X4 they hit the DS but on another 4X4 the cleared with no problem. They sent me another one that was bent more away and after I swapped that one out, they paid for the shipping back. Did it once more and it is fixed. I even sprayed paint on the front diff U joints to make sure but it was fine. Then I had to fix a rattle on the right side. turns out to be a clamp bolt hitting something. Cranked it away and alife is good.

 

They need to update their website, so just give them a call. Part number for the new 4x4 headers is 70-2265 (uncoated). I'm sure the coated ones would be 70c part number just like all of the other coated ones are...

 

But Dynatech is plug and play. No cutting, welding and everything is there. No coating needed either
