Neighbors give you the 'stink eye' when you cruise by? Buddies won't ride next to you any longer? We know you aren't getting any older (so we won't ask.) Let's face it… you purchased your Brock's Performance exhaust because it performs, looks and sounds BADASS, but there are some occasions when that sound needs to be kept in check, and you are mature enough now to give up a few ponies, if you can keep a reasonable tone. Well, Brock has listened to your requests, and he and his team have developed a good looking, quick and easy cure for your 'hum in the drum'. Our new Noise Suppressors have a fantastic ability to curb the noise, and they install in seconds (and your ass-dyno probably won't know the difference.) Your ears, however, will definitely notice a reduction in noise, without completely trashing the sound we know you love (and that was our goal.)

    Works well

    The suppressor works very well and put the sound volume at idle and steady cruise right where I wanted it. The volume does increase and sounds good when accelerating hard but nothing like when there is no supressor installed. The product does look a bit like an afterthought but does work and it is pretty cool that you can install it and remove it within minutes if you so desire to completely change the attitude of the bike. Sound volume wise it works great and the looks of it are growing on me.
