I was doing searches for info on the power tip for Two Brothers pipes and I saw references to the P1R and that it didn't do much. When I went to the Two Brothers site there wasn't a P1R but there is a P1X.

It looks a bit different than the P1R that everyone said was ineffective.
I saw a review with comparrison videos on a GSX forum.

Looks like good stuff.
Has anyone else had experience with these? I think I'm going to pick a set up.

Our P1-X PowerTip? sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A straight-through sound diffuser, the TBR PowerTip? quiets the pipe about 7-8 dB with no significant reduction in horsepower.
