I got a e-mail response from Dale at Specialty Spares about toning down the exhausts. If your baffle material is still in pretty good shape, you can tighly wrap another layer over the top of what's there. Either tape or wire in on and reinsert. Be sure you buy 4-stroke exhaust wrap not 2-stroke. The more you can wrap the more it will tone it down and still have a nice throaty sound.
