Mufflers are all rotted out (took 30 years but they need replacement) does anyone know off hand the diameter of the header pipe? I was thinking of gutting off the welded header pipes and just slipping on 4 fish tail pipes which should look cool and give bike that "Harley" rumble.

Don't know the size off hand but I fitted a gl1000 with a pair of "Harley take offs".
I used a coupler from Autozone.
Sounded fine.

I had the same problem with my `82 1100 naked and did it this way. From NAPA i got 2-2" to 1 3/4" reducers to weld to the stock headers that i cut at the factory welds and ground them for no sharp edges, tapped the reducers on with a dead blow hammer, had them welded, then tapped on a set of H-D 1540 dyna-glide mufflers and clamped them down with the H-D pipe clamps. I used JB Weld and 3/4" freeze plugs to fill the crossover outlets. One thing further, I had the 32 yr. old headers re-welded on all the seams, the welder suggested this because the header is a split plenum design, then painted them high temp. black. I chose to tilt the reducers up about 20 degrees then welded, which provided me with a good looking upswept system and i was able to reuse the honda muffler brackets to boot! DON`T SPARE the LOCKTITE mounting the brackets to the harley mufflers. The muffler tips point towards the turn signals and a little below. Oh and the sound is soft and mellow til the revvs have built up around 5000 rpm then they start to sound mean. Hope this helps, and all it cost me was about 3 hrs time and $65.
