well i have oredered my exhaust for my 02 R1 i bought into the yoshi tri-oval Ti race slip on. i have the regular RS3 oval race Ti slip on on my R6 and was really impressed with sound quality. idle is nice loud but not nerve racking loud. getting on it is an amazing sound of just screaming i gonna pass you noise! i have a buddy witha a gixxer 1000 with the tri oval it sounds basically the same but i distinct sound in high RPM's. I ordered through STAR CYCLE.com some people have problems with them but i never have they always cut my a good deal and beat anyone's price on anything if anyone else ordered through them they got all there yoshi 02 R1 pipes in today March 19. they even sent mine one day mail for free. can't beat that! also what ever there internet price is they will come off of it! for a sale. and oh SPRING BREAK is in FULL force in PANAMA CITY:boobies :boobies :boobies :boobies
