i just ordered my custom big bore raptor 660 exhaust. its actually a trail n drag setup like the 700s have but out of frame for the 660. mike is a great guy to deal with. i will post pics when i get them. he said it would be @ 1.5 weeks before he gets them done and able to ship to me. i will keep everyone posted on this first big bore 660 exhaust.
