I pondered the decat concept for a long while, as there are so many 'cheap' options. After watching the dyno results and seeing the disappointment on faces of 790 owners who opted cheap, I ordered the Arrow from Will at Rottweiler. Sound is awesome, with no loss to low or mid range. The Arrow decat mimics the stock cat, and just fits easily and when you fire the bike up you really notice the distinct sound. Thank you again Chris, Will and Jessica D. My 890 Rally sounds like a dream.
