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.
