15006B – Exhaust Muffler LeoVince CLASSIC RACER Black HONDA CMX 300/500 REBEL (photo below)
OWNER COMMENT : To me, Leovince (classic Racer) sounds better than the Arrow. … Arrow with original baffle : Quieter than stock exhaust
Arrow with larger arrow baffle : Nice sound with a low bass frequency, trying to imitate a V-Twin
Arrow without baffle : Same sound but louder and a lot of pops and crackles, absolutely not legal in term of volume. …
Leovince with original baffle (52mm): Nice sound at low revs, too quiet after that, but legal.
Leovince with a generic 48mm baffle found on amazon : Better sound ever on my 500, more like a classic motorbike from Triumph I would say, and could be legal
Leovince without baffle : Barely same sound as a Vance and Hines and louder then Arrow without baffle. Like it but my neighbors won’t.
Some cars (such as VW GTI, Audi S3, BMW, Lexus, and Mustang GT) play the exhaust sound through the audio system so the driver can hear the engine sounds better.
If your motorcycle exhaust is too quiet for you, you could make a metal deflector that would go underneath the muffler outlet and reflect sound back to the rider, so the bike would seem louder to you.
