Is a Ninja 250/300 with a pipe. Sorry, but it is. Actually, I'm not sorry, this is a public service announcement. Sorry, not sorry. Sure, your 2 Bros carbon fibre shorty muffler may have a nice meaty growl at idle, but as soon as the revs rise, it becomes an unpleasent screaming upper register ear fcuking offence that you should be ashamed of, much akin to a mewling transgender (post op) prostitute who has done the deed but not been paid. Is that what you want to sound like? Just don't. Tell the dealer to keep the pipe, you'd like a cheaper price & put the money into training or better gear. If you have one, take it off & throw in a lake & put your stock pipe back on. People will stop trying to punch you, your acne will clear up & you will lead a rich & rewarding life of not being an obnoxious douchebag. I have long held this view, but it was hammered home into my brain via my eardrums last night as I cycled home on St. Georges road, as a rider was attempting to split the moving traffic, rather unsuccessfully, first accelerating hard in first gear into a gap, then braking very hard as the gap dissappeared, ad nauseum (literally) all the way up St. Georges rd, all the while going slower than a bicycle. Admittedly, slightly faster than the surrounding traffic, but if you're making the racket of a thousand dying cats being put through a woodchipper, you'd probably like to moving slightly faster than a bicycle. Just say no. After all, if loud pipes save lives, imagine what learning to ride the thing could do.
