An economical solution to the problem of hooking-up hedders to an existing exhaust system. No longer will the hedder installer have to fabricate hedder hook-ups from scratch.

Shorten the length of the diagonal length to adjust the amount of offset required to allow for clearance of drive-shafts, cross-members, brackets, braces, etc.

Weld the threaded O2 sensor bungs, included with these kits onto the S-bends, once the optimum location has been determined.

Available for 2-1/2 and 3" exhaust systems. The universal flanges allow hook-up to virtually any hedder manufactured.
