Got my S tips installed today, didn't come out to bad. Basically I grounded the single tip welds with a dremel ( 4 spots, 2 inside and 2 outside) and then took it off and cut the pipe flush with the muffler with a Sawzall, and then just welded the tips on. They actually sit an 1/8 of an higher than the oval tip.
