So I have a stock YZ250F with no spark arrestor on it. I think noise wise, it's not too bad, but it needs a spark arrestor.
I have a DRD aftermarket exhaust system that came with the bike that i've yet to use. It does have a spark arrestor, but the guy I bought the bike from says its pretty loud. I've tried to find noise level readings for it, but have nothing so far.
So it sounds like most riding areas in the interior will be getting cracked down on….will the DRD pipe and exhaust pass the test or should I be looking for another option? I could fab up some type of screen for the stock exhaust….or am I worried about nothing?
Good for you for the interest, there are still many guys out there running extremely loud bikes and it is the number one problem and yes they will be cracking down more often. Unlike the days of old louder does not mean more power. On my yzf250 which is over the 96db, I uses a db dawg, 50 bucks and solves both problems. Or go fmf with a stealth and it will sound cool but way quieter. If you go to Bear Creek or a track get someone to test your bike. I got my 350 tested there and it was 93, and a stock 450 suzuki tested at 118 if you know something about how db is calculated 118 is like 5 times louder as a person would recognize, crazy…if you wanna hear when your older get a pair of ear plugs even if you bike is under 96…and you ride a lot…
