The photographs are Dr. Jekill & Mr. Hyde's own of the Twenty-One system. They publish no rendered image of this exhaust with each end cap, so the picture does not change with the cap you choose — the part number and the price do, and they are what we order against.

Header set

On the Harley-Davidson Softail 2018–2020 Dr. Jekill & Mr. Hyde supply the Twenty-One Wrinkle Black only with their Twenty-One header set. It replaces the stock headers, so it is part of every configuration on this page; you choose its finish here — 21 Full Forward Narrow Brushed, 21 Full Mid Narrow Brushed, 21 Full Forward Narrow Wrinkle Black or 21 Full Mid Narrow Wrinkle Black. Forward and Mid refer to your bike's control position; choose the one that matches your footpegs.

Built to order

This exhaust does not exist until you order it. Dr. Jekill & Mr. Hyde build it to this specification after you order, and it typically reaches us in 3 weeks, up to 6. Because it is made to your specification it cannot be returned or cancelled for change of mind once manufacturing has started; if it arrives faulty or not as described, your statutory rights are unaffected. Once it arrives with us in Leeds it is dispatched like any other order.
