awww...give the poor guy a break. I had four different exhausts on my '03 GSXR1000 before I settled on the Blue Flame dual outlet can. For me an exhaust is mostly about looks and sound, When/if Taylor made comes out with that GP exhaust for the '06,I'll lose the M4! I don't really care about the 3-6hp you might gain. If going faster was the goal then $1600 would be much better spent on; suspension mods,track days/classes,a gym membership- lightening the rider/bike package,engine mods,trading the Honda in for something fast like a GSXR.....
