Wow!! That does look like a pretty complete kit. The only thinbg I don't see in the pic is some dust shields for the rears. That's an awesome price. I think that's what Classic Ind. gets for the rear kit only from SSBC.
I think those round race pro muffs are pretty rowdy. Almost everybody I have heard of that bought them changed their minds after because they were too loud. Tailpipes seem to make a big difference as to how loud muffs are though.
