I am in the middle of installing a Rinehart Header on my '19 Tri Glide Ultra. The part # is 100-0452, the #'s were confirmed from Rinehart and Direct Cycle Parts. The header is installed, losely as I was about to start making connections after the header. The problem is that the pipe, from cylinder #1 is about 1 inch from the rear frame. There is absolutely nothing that can be connected to the header pipe. The #2 cylinder is fine with the crossover pipes etc. So that is the issue I am having and want to see if any else has had had similar problem.
Thanks

 

That pipe does not fit a Tri Glide. From what I can find, it's for two wheel model M8 touring bikes. So that is likely why things do not align up.

And, if I recall correctly, the Tri-Glides use the same size muffler connection on both sides. Where the 2 wheel M8 Touring bikes use a larger inlet on the right side muffler.
