We worked with SuperTrapp to develop their new full system for the Monkey, and they're now in stock ready to ship. Wonderful tone, great power, and an esthetic that plays so well with the bike. Additionally, it's completely tunable via their patented discs to tailor power delivery and sound, as well as fuel demands, making it a bit easier to work around a stock ECU if needed. https://mnnthbx.com/product/supertra...ust-pre-order/
