I like my oem exhaust. Quiet, doesnt need a 175$ accessory to run right, and i wouldn't use the benefits of 7 more hp in any good shape or fashion on the street. There are plenty of riders here that will ride circles around me or track their bike and need every bit of garnered horsepower they can find. Or, they just want a better looking or performing exhaust. Or they want to get rid of the stink.
If i had to replace my exhaust, id go the low slung 900rr route mearly for the fact that its tough to run saddle bags with our exhaust without melting things. I might be in a weird crowd but i dont like loud exhausts. Just my .02.
I may not have a lot to say but it doesn't mean I don't listen.
