I am more aware when in the cage hearing an exhaust, but i'm a careful driver bike or car and always checking mirrors and before changing lanes always head turn even if sure nothing is around me. wish could say the same for most other drivers/riders. some sportbike exhausts that are loud in my opinion sound good but many SS types just sound like a loud angry wasp which is annoying. then again many cruisers with loud exhausts sound like crap too though a good sounding one i love listening to. my last cruiser (vtx1300c) i put cobra lowboy staggereds on and took out baffles and was loud when i wanted it to be and fairly sedate in residential nieghborhoods. This bike i'd like a LITTLE more sound but not a straight pipe loud that along with horn (which i find if needed it's too late to hit, ie: i'm emergency manuevering) will be enough. any help we can get on the road to be seen OR heard is an improvement on our chances of continueing to ride safely, the most important is OUR anticipation that other drivers and riders are going to do something stupid.
