Header Flange
Just installed newstainless shorty headers, Got new exhaust on, now the passenger side header flange rubs my frame most of the time when I accelerate. I got underneath, and looked, there is a little clearance between the flange and frame, but you can see where it comes over and rubs, anybody have any ideas on how to fix, thanks

RE: Header Flange
Mine did that also. What I did may not be the best idea but it worked just fine with no ill effects,..
I raised the truck up with my floor jack then, took a 2x2 cut at about 2 ft and stood it on end under the
floor where the flange was rubbing. Lowered the truck slowly so the 2x2 flexed the floor up less than a
1/4'. When I released pressure by jacking back up on the truck, the floor flexed back half that but, it was enough
for the header flange to stop rubbing.
