I've got a full Yosh on my '04 R6.
As far as making a "custom" mid-pipe, I say go for it. All of this BS about the mid-pipes being manufactured by scientists is a load of hooey. It's not like your bike is going to blow up because the mid-pipe is 1/32 larger in diameter and 4" longer. I just helped a buddy mount his Micron can to an Erion Racing mid-pipe, as long as it fits let 'er rip !!
