For you 4-stroke riders looking for a quiet exhaust system that doesn't rob power, there is such a thing. I found this tidbit on another forum by a fellow named "Scoobydoo", and felt compelled to pass on the info regarding the CRD exhaust system. "........they are French and heavily involved in the four stroke Yamaha 250/400 world enduro championship team. They make a pipe which they claim to pass the FIM noise test of 92 db!!! but still makes the power. Their website is www.crd-international.com "
Note: this is the system used by the UFO/ Belgarda Yamaha Enduro team, including: Mario Rinaldi, Peter Bergvall, and Stephan Peterhansel, on their WR250 and WR400 race bikes. To see the awesome machines at the UFO website, go to: http://www.ufoplast.it/resME.html
