View Full Version : Quiet pipes for HS
07-03-2006, 01:40 PM
I was wondering what racers who have 06 crf 250's were doing to meet the sound limits for next year. I looked at the FMF Q2 and it is a one sided muffler and would have to change the enitre back half of the exhaust system.
Does anybody have any ideas?

Hey Jared You should check your crf first. You might be surprised and find it will pass in the stock form with them properly packed. My 05 CRF450R passed and it sounded louder then the CRF250 twin piped.

twin pipe crf250's dont pass their close but over 99-100 db's
Is there a list of bikes and their stock readings somewhere?
