headers?
I have a 03 qc 4X4 with the 5.9 magnum rare i know. I am looking for headers to give me a bit of a increase in power for towing. I would like to get the short ones so i don't need new exhaust, but I cannot find too many listed on sites. Any help is appreciated!
i just ordered these am i gonna have any problems with a cel or is it just gonna bolt up and be fine?

I have had the hypertech for a few years but can only run the regular tune because of pinging issues, even with 93 octane gas. My gas mileage did increase from 10 to 11.5 with the programmer i hope the headers will increase it a bit more!

Ditch the hypertech and try the flashpaq. It claims over 40 hp for the 5.9.
yeah the SC is way better for the 5.9....i'd deffinitly look into getting lockin header bolts otherwise get some RED locktite and put some on the bolt threads when your putting the headers in, tighten em down and you'll be solid
I did get different header bolts and better gaskets, the flashpaq is nice but its just a truck im not out for racing i tow alot with a 16 ft trailer with 2 bikes thats why i got the headers to help with power.
