Dr. D, where's the quiet exhaust system???

C'mon Doc, there hundreds of people that are sick of going deaf in the woods, make a quiet exhaust, why wouldn't you????

i'd buy one

I would love to have anything quieter, that I wouldnt have to give an arm and a leg for!!

I WANT IT ALL, WHERE DO I FIND A SPARK ARRESTED EXHAUST FOR MY YZ400F THAT PERFORMS BETTER THAN STOCK WHILE NOT GETTING LOUDER?
