I got a pair of RUSH from Value Accessories w/ the 2.25" baffle, they're not too loud. Lots of choices on tips, 3 choices of baffles. You can swap out baffles 2.00", 2.25" & 2.50". Fair price too. Beware, several RUSH venders sell the pipes cheaper but they don't come w/ tips. V.A. are honest & straight forward & their pipes come w/ tips.
If you don't have torque loops, you should give serious thought to putting them on. They'll get rid of the drone. Loops are a PITA to put on.
