I just called pacesetter and they told me they have never test fit them on a 2500HD with the lq4 6.0. They said the've only been done on the ss trucks. Is anyone with a HD running these headers on here or does anyone know wheather this is true or false

Thanks guys

 

i just had a set put on mine and they went on no problems except for a broken bolt. These headers kick ***, good investment.

 

How much welding or fabrication did you have to do? What type of collectors did you use? I am debating on Pacesetters or ASM's for mine just wondering how much work it's going to be.

 

I had a muffler shop do it, they welded in 3" tubing from the collectors to the existing pipe. The driver side had to be custom bent to clear the d shaft and tranny but it all ties back into the oem exhaust.

So when you installed it where did you cut of the stock exhaust system at. Do you happen to have any pictures I could see

Thanks

 

Thanks for the info. Should be getting mine before to long. Got any pics of your setup?
