Are you close by? You can stop by my place and we can try the other db inserts I have here, they should bolt right in.
I'm very happy with the tone coming out of my pipe but then again I'm using a different insert then you have.
I haven't received my SBK yet, but am concerned about the noise that others have reported. My hearing is diminished these days from a long history of riding loud bikes and shooting. I wear ear plugs when riding, but want to lessen the chance of additional hearing loss. I can't find any mention of db inserts or spark arrestors for the SBK on the Leo Vince web site. Can you give me a lead on the availability and price of these parts?
