I would like to welcome K&B Supply to the site. K&B manufacturers exhaust silencers that insert right into your exhaust tubes, have no affect on performance, and can silence engine/exhaust noise up to 75%. They are an OEM manufacturer for exhaust silencers and diverters used in new boats. The silencers are only $88/ea. Please buy 1 or 2 and let us know how they work. Thanks K&B! http://www.knbsupply.com/insisy.html
