slice Posted April 26, 2014 Share Posted April 26, 2014 How loud is loud? unless you have a DB tester there's no way of telling is there, you could try standing it next to another 400 and comparing them but unless you know someone nearby that has one that's not a solution is it, as long as the silencer is original equipment and all the baffles are intact then it should not be a problem.

Moderator Cynic Posted April 26, 2014 Moderator Share Posted April 26, 2014 Dont worry about it. The bike isnt new enough for noise rules. So long as the exhaust is complete and not leaking go wake the dead. Link to comment Share on other sites More sharing options...
blackhat250 Posted April 26, 2014 Share Posted April 26, 2014 As cynic says,,, no limit , as long as exhaust has " Not For Road Use" stamed on it ,its legal,,, is it induction noise,? or take out the baffle and Wrap it ,, Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted April 26, 2014 Moderator Share Posted April 26, 2014 As the answers above, it makes no difference. Loud is good on a dirt bike. Link to comment Share on other sites More sharing options...

dt502001 Posted April 27, 2014 Share Posted April 27, 2014 With any 2t motor the bigger the cc the deeper the sound is,if your worried about a coper giving you a hard time 1st dont as said as long as it not stamped not fo road use your ok. You can get apps for a smart phone for DB testing they aren't 100% but close enough to let you know if you want to know.Alot of the tracks here now have a 98 DB rule but if your smart phone shows 98 and the tester at the track shows 99 they dont give you a hard time the first time they just tell you make sure it meets next time Link to comment Share on other sites More sharing options...
