I have an '05 AWD Silverado SS and I'm curious as to what all headers are available. There are at least 10 solid options for LS1 cars but I can't name but 3 that I know fit my truck. Is there anything else out there other than these?

Dynatech
Pacesetter
OBX

 

doug thorley i believe

 

I think Hooker makes headers for your truck also

 

Money no option Dynatech's would be my choice.

 

Almost forgot, StainlessWorks also

 

Pacesetter
OBX
Dynatech
Stainless Works
Doug's
Doug Thorleys
Hookers
AEM
ASM-but they're discontinued

 

ARH. Newer sponsor on the perftruck site. But not ls1tech. Makes them as well.

 

Has there ever been a dyno comparison between headers before? I did see where a guy swapped out between Pacesetter LTs and Hedmans on an engine Dyno with an LS1 and gained 12hp and 17tq.

Also has anyone ported the truck intake to see if there are any gains there? I know they're so close to an LS6 it's not worth the trouble to swap them and I've heard a ported LS6 is better than a stock Fast.
