right, i wanna get a bit more kick out of my er-6f, apparently getting a custom exhaust can do this (i really know nothing about vehicle mechanics) so where should i look? how can i found out how much extra juice i'll get, the volume levels and the costs? also looking for rear huggers for the back wheel, to help keep dirt out of the back of the bike. Where can i find these? I'm based in Adelaide so local places would be nice also if i get these fitted, will the kawa dealer be okay with these mods when i take er in for a service?
