I'd like to see how to remove the flapper valve so I could just run slip-ons. Thanks.
 
I'll take pics (Fml autocorrect lol) of what I did to mine this afternoon Thamer. It's real easy.

Thamer,
First grind the flapper of the CrNi axle.
Than I removed the flapper valve with a dremel tool and a few small dremel grinding disc.
I divided, with the grinding discs, the CrNi axle in 3 parts, I could take the axle parts out from the inside.
On the left side there is some kind of a graphite seal in which the axle rotates, I took that out and I used M8 x 20 mm CrNi hex bolt and a CrNi flange M8 nut. I used two annealed red copper rings on in and outside to seal the bolt and nut.
It works perfectly
 
Davyc, what did they exactly change on the Db killer, did they make just a smaller hole?[/

They fabled a sleev which slips over the existing baffle cylinder.
Sinew cans said they didn't want to do any more mods as this may cause issues with the bike.
Conclusion is no more standard track days only +102db or acu testing days.
 
I will take a few more pics once I remember them from the bike later this week
