Well Dg is usually the same design as the stock pipe on other models just chromed. Most pipe manufactures offer a quiet core insert to keep their pipes in the legal racing decibel range which I think is about 98 or 96. Make sure you keep the packing fresh as this will help a lot.
keep an eye out for leeks in the head pipe or where the header and canister meet as this will produce a loud crackle. And think of it like this all quads and toys with high compression motors are going to be loud in a neighborhood to a certain degree due to the amount of homes and cars/trucks for the sounds to bounce off of and make it seem louder than it really is.
My suggestion is to see if DG offers a quiet core for your pipe and if they dont go with someone like HMF who does and can keep it under 98 db. And no more bashing two strokes - deep down you know you wish you had one - nothing smells better than one burning vp and polluting the air. lol
