I gutted the original exhaust on my uly, using that photo above. I cut the rear completely off as everyone else does.
At the front, i cut from each side with a hacksaw, just enough to cut the two tubes off, kind of left the centre pipe and the middle of the muffler intact. Made it easier to weld up again and keep everything straight.
I have an '07 with DDFI-2, so it ran veery lean, but sounded OK.
Watch out when fitting after-market cans to a ULY, I've since installed a buell race muffler, and they were never offered for a Uly. I couldn't understand this, cause the motors should be exactly the same. After I fitted it, I jumped on to go for a ride, and the bloody side-stand hit the LHS Outlet.
That's the only reason it won't fit......the ULY side-stand is a coupla inches longer than the lightning, cause of the extra height. I think Micron had a separate part no for the ULY, maybe for the same reason.
So, if you look at after-market, check the side-stand clearance!
