THANK YOU for clearing up the question of the presence of packing in the 03/04 stock silencers! The dealer couldn't even answer that one... This however presents a problem.
I am an older guy, sport trial riding, no racing so quietness is more important than high end performance. Just bought a used 04 WR250F w/ 300 hours which has the stock 5TJ-00 stamped at 82db, but it is way louder than that? and not sure why.. Do these things burn out, even if they have no packing? I live in a very uptight Massachusetts suburb who calls the trail police on me if they hear me on the trails much. seriously, 3-5 uniformed guys on ATVs.
I need to make this bike as quiet as possible (lower tones are better) and would hope not to rob it of all it's power.
Would anyone recommend (keeping in mind that lower tones are better):
1) buying a stock 05 silencer and possibly modifying it?
2) shoving packing into the 04 (even though it isn't supposed to have any)?
3) buying an aftermarket like the FMF Q or similar?
4) or a better idea??
Very much appreciated!
