looks good... would like a set for mine!

 

Those are definitely on my "someday" list. Are you sure the flanges are 3/8? They look thicker in the photo. I could be wrong, but most other high quality header companies seem 7/16 or bigger.

 

Anyone have a set of these? The look like they could not be made any better. That flange in the photo has got to be thicker than 3/8 inches, look how fat that flange is.

 

Top notch for sure..

 

So... one set of primary's travel under the engine???

 

Hello ig109, somewhere on Dieselplace.com, in the GMgassers section, a guy did a thread on his install w/photos. He did a nice job. Yeah, the passenger header tubes go right under the oi pan/converter shield area, just like the the factory head-pipe.

 

Those are some good looking headers
