Supertrapp (ST) Supermeg with ST Trapp Cap end cap. I switched from a V&H ProPipe. Loved the look of the V&H but it was too loud. The ST has "disc technology" that allows a wide range of sound levels and back pressures. Fit and finish of both V&H and ST are excellent.

Some kind of end cap is required. In pics, mine is an "open," which means louder and less back pressure. Where open end caps are used the number of discs seems to have limited effect on sound level. Where closed end caps are used more discs = louder. But even at a full compliment of discs with closed (i forget how many but it's a lot) it's quieter than any open setup I've tried. The flexibility to tune sound is pretty cool. I do run closed a few time a year, particularly for long trips. I don't have to worry about re-tuning because of the Thundermax.
