If this post is in the wrong spot, please delete or re-post- Hi- My name is Randy Hyden and I'm a product specialist for Leo Vince exhuast, and a DL-650 rider. If I may ever be of help to anyone on the forum, please feel free to email me at firstname.lastname@example.org . I am not here to spam, or sell exhuast. My intention is to assist with questions about performance exhuast (not just Leo Vince). If you are ever looking to purchase product, I'm happy to refer you to one of our prefered stocking dealers.
