Online Editor Brian Hatano installed the 50-state-legal Indian Accessories Stage 1 Straights Slip-on on his long-term Scout project bike and rolled it onto our in-house dyno for horsepower and torque numbers, and also to record the new sound. <br /> <br />The Straights produce an exhaust note that is richer and throatier than the stock exhaust note. It is SAE J2825-compliant and certified to meet CARB emissions standards and also includes EFI recalibration by Indian Motorcycle dealers.
