Looking to try a different box exhaust on my p200. Running a BGM big box on one bike and I like it (mallossi cases, mhr top end, 60mm pinasco crank...)

Wanting to try something other than a SIP 2.0 on my other bike (ported stock top end, mhr piston...)

Interested in the polini, another bgm, LTH, any box besides a sito plus or sip 2.0. I ride with a passenger quite a bit and rarely push the bike to top speeds, I am mostly interested in good torque.
