Sweet exhausts!
I've been looking for a nice exhaust system for my 2004 Kawasaki ZX-10R and I've finally found not one, but two! I first found Micron's new GP exhausts. These are really nice looking hydro-formed exhaust systems. Because they're hydro-formed, they can get the diameter of the pipe just right and every point in the exhaust. This allows for the most horsepower available. They don't have one for the ZX-10R yet, but one is supposed to be forthcoming. The Bostrom Brothers (Boz Brothers) have an even nicer looking exhaust coming out which stops at the lower fairing. This is really what I've been waiting for. An exhaust like the Buell's...all underbody. The only downside to this is that it is really loud, around 115-120dB. You can get a "muffler" insert, which will reduce the dB's by about 5, but this still isn't enough. They supposedly have a quieter muffler to be released soon. If they can get the dB's down under 100, this is the exhaust for me.
