DR 650 muffler mod

Hi Slapper,
It is only slightly louder than stock.
I was looking at also making the outlet bigger (for a bit more noise & hopefully performance) but this will take time & more Dyno runs to see how it is running (Tune).
The current mod I do works very well (Is noticable difference over stock in performance, & Torque up to 10%) & have done Dyno's so we know it is running well. (Proven Product)
In fact it was independly tested by Cycle Torque Magazine in Sydney, & the tester was so impressed he wanted one for himself.
This mod was specifically designed for those who want to keep the bike quiet.
Hope this answers your question.

I'd like enough noise that I can hear it over wind noise - but I don't need any more than that :)
With just the snorkle out and a stock exhaust, I'm finding it difficult to hold road speed and I suspect it's because I can't hear the engine rev's - so a little bit of noise would be good, but I'd still like it to be "quiet"
