Over the past four months, Testbike Manager Michael Candreia and I have been bolting on parts-and lots of them. I worked with Scorpion early in the development of its Tiger 1050 exhaust. We went through a few pre-production examples before settling on the one pictured here ($361.95 from www.scorpion-exhausts.com). This European-spec model features a dB killer that limits sound to pC (though more entertaining than stock) levels, and can be purchased separately and installed with minor modification. Muffler cans are available in stainless steel (shown), carbon fiber, titanium and "flame" titanium. Scorpion engineers its exhausts with three main goals: proper fueling, better midrange performance and a "nice, deep note." Better sound, improved looks, roughly 6.6 fewer pounds, no EFI quirks to note and the seat of my pants says power is improved as well. That's not yet dyno-confirmed, however-stay tuned.
