Thunderheader Modification
Thats exactly what it is. It's the newer style pro pipe, just has plenty of miles on it and I used the heat shield from the PP for the muffler. I cut the TH muffler off a Sportster I got clean and cheap for 200 bucks. Welded on a slip fitting (so I can change it back to the pro pipe if I didn't like it or it didn't perform or whatever), then slid it right on and bolted it to the propipe mount. "bolts" on damn near perfect! I think I have one more pic from mock up stages....

Would a softail 06 Thunderheader would fit 1200cc sportster 06?
On their website the reference is 1027 for softail and 1028 for sportster.
My question is does the motor has the same fitting?
