TTI Shorty Headers

I have the TTI shorties on my 340/727 Dart, and on my car the TTI headpipe on the left side interfered with the kickdown linkage. Had to modify one of the bellcranks and one of the rods had to be bent. They do not mention this in their instructions. Also, if you do buy these, attach the head pipes to the headers before you put them on the engine. Otherwise the nuts & bolts on those adapter flanges are a PITA to get too. I think I had every wrench, socket, and extension I own under the car, and it took forever to get all the bolts tight.
