Reply to "#5177 has left the Barn"

Dear JFB,

         I have had driver's side header primary interference by the motor mount and gas tank on two sets of GTS headers over the years.   On the first set, I discovered years later that the BFH approach was used to obtain suboptimal fitment.  With the recent second set, I was smarter and checked with an exhaust expert.  His method is to heat the area of interference with an oxyacetylene torch to orange hot and while the steel is relatively soft, then apply a round (various diameters available) to the problem area followed by judicious whacks with a BFH.

         The common BFH method applied to cold steel, in my experience, results in a mechanical reduction of ugly appearance.  The oxyacetylene BFH and round tool combined with a BFH produces a better esthetic result.

           Obviously, not many people will observe such things given the location of the corrections on the primary tubes.   Also, my headers were not stainless steel, which may be a important point.   It is good to know your options.

                 Warmest regards, Chuck Engles
