[cbucgo]

last year i didnt see them that much but when i did they sounded awesome. this year i have seen on just about every bike i look at. are they a good pipe.
i am into d&d systems because of the sound and need to put a pipe on my new 2001 r1. what do yall think.

from what i understand they are actually a sister company to D&D although very different... pretty good looking good sounding pipes and not too expensive, and they come in high mount too if you like that

ya...i have heard one on a 900rr and it sounded nasty......i just dont know if i am into their look yet. i like the d&d and mig hount mounts.

one of my fav pipes! i like the M4, Micron, and Scorpion the best, ill prolly go with Scorpion cuz of the cost..

heard M4 sound pretty nice.. have a few clips of em, but on a vtwin
