Anyone got any pictures of the dynatech header install? I'm looking at the underside of my 04 GMC Z71, and it doesn't look too good for getting them in there with the cats, and everything else.

 

get in touch with 03GMC

 

i did my install on my 04 silverado SS, so should be the same, what are you specifically asking about ??

 

Actually...once I looked at the pictures of the whole Dynatech system, I kind of answered my own question. Thanks,

 

I hope you can weld. My dynatech system was almost 4" longer than stock, I had to shorten the crossover tube and the cat flanges to keep it from hitting ther crossmember, then cut and re-weld the collector shortening it 2.2" to fit to the muffler flange.

 

I have a tig machine in my garage, so I can do pretty much anything I'd need, but don't want to fool around much during the install.

 

maybe it'll fit your truck better, but there was no way to get the dynatech's in w/o modifying them, I've got a MIG at my house so the fab was no prob. but its a PIA to change out the spools from to stainless and change gas tanks.
and I would expect a better fit for the money spent.
