My riding is 99% trail or horse trials (but with considerable road miles as part of the trail riding) and, for good or bad, my 400EXC is a 'keeper' as changing it for a different bike isn't really a justifiable option. I've also spent a bit of time and money getting it right for me.
Partly due to most trail type bikes being relatively small, physically, for my 6'3 and, being about to retire, I not in a position to chuck a few thousand at a new bike.

The only issue I have is that, even with the standard exhaust, the bike isn't over subtle, and it would be good to lower the db level a bit.
I have stripped the silencer down and the packing is fine so it's not defective silencing.

I'm not a believer in loud is safest, even very quiet bikes can be heard and I'm sure any reduction wouldn't render it as quiet as an electric bike.

So...has any got a db killer or can recommend one?

Db dawg if you Google might be an option.

I'm trying them David but they are only available in the US now and the sizing doesn't seem to work very well. They are all huge diameters.

$60 + delivery is a bit risky so I might try an email discussion.
I suspect their silencers aren't the same as ours either and past experience with US sites means they can be as thick as two short planks.

Not to good for trail riding then

Almost thought it was Flynn returning under another name. Could be?
Please don't go trail riding with a silencer that loud.


I have gone the re-packing route as that seems the most viable option.
DB killers seem to be unavailable because they probably ain't much cop.

TBH it's only loud when I give it some gas most of the trails I use I just like to plod and look around ;) and Enjoy the country side
