im a newbe here but have been learking around for a bit. I have found a lot of reports on LT headers but haven't found a company that everyone is a big fan of. I'm looking for something stainless or at least coated. Also with Cats or soo called cats. My truck is an '04 Chevy 2500HD with the 6.0L in it. Can someone shed some light on what company has the best fit and finish?

Thank You

 

if you want real cats go with the dynatech long tube headers and catted y-pipe stainless too

if you dont need cats get the pacesetter lts and ory ceramic coated

if you want gutted cats get pacesetters ceramic coated and use stock y-pipe( i think that will work)

 

I think moregrip has stainless works headers. Does anyone know if other brands fit the 2500HD's ok?

 

Pretty much everyone is a big fan of Pacesetter and Dynatech...

 

dynatech seems to have the best looking header...

I bought a set of used ASM's and they still look like new

 

egay has the knock off dynatechs...good reports, bit louder w/o cats...

 

thanks everyone! i was debating between the dynatechs and stainless works does anyone know what company has a better fit then the other?

 

...and then there are Thorleys....

 

moze- do you have any pics of Thorley's? also where did you get them from? how was the fit?

 

I have heard that Dynatech has excellent fitment (see high-priced)...
