Please do. Still trying to think what end can i want with my DT. I want it to sound as deep as possible rather than tinny and whiny like my mates RS125. Haha that's just annoying :P
peg the ypvs open, from what I have seen the best sounding bikes have the ypvs pegged open they have a short pipe with a small hole or a long pipe with a wide hole, the dep that I had was nice, with a gutted stock exhaust and some of the baffle material removed (off road use only of course)
I have mine pinned open and no snorkle and sounds quite deep when in low rpm sound 100 times better then just without the snorkle on.. try taken out the snorkle under the seat and give it a rip up the road an back with no helmet on just to get a good listen or get someone you trust to just give it a quick rip up ur raod and back.
