Harv, why don't you ask MaekT if he can make or already has some silencers for the pipes on your bike?
I know when Steve K (IA) has them in his pipes it makes a hell of a difference.
I have followed him with the silencers in and also out.
One has a Nascar rumble and the other is quiet like a mouse.
It would be worth a call in my book.
I agree with RJ, contact MarkT.

My M2W pipes with silencers are quite pleasant. FWIW
