Arrow 3-1 Lowboy sound test on my 2011 Triumph Speed Triple. This is the full titanium system, including headers, mid-pipe and slip-on. Unlike the stock mid-pipe, there is no catalytic converter, so not only do you save 19lbs of weight, but you gain 8-10HP with the proper factory tune. This exhaust is designed for off-road use only and might be illegal to use where you live.
