Don't worry El, I can't wrap my head around metric. Hell I can't even wrap my head around standard.

Out of all the pipes you can still buy the DG would give you the best woods performance, but it would not be a whole lot better than the FMF.
Try the torque rings they are easy and cheap and it doesn't take much to make a difference in that area.
Cutting the pipe is a option, but say goodbye to the plating and it is tough to add, it is easier to remove and that can be hard to do because everything gets thrown off.
Your biggest improvement at his stage is port work and a reed spacer. I think you changed the reeds correct? Also making a few shims or a couple of long spacer here-

I was able to take it out yesterday and wow. what a difference the right jetting makes. I lowered the needle on clip and dropped from a 410 main down to a 400. I went from 1 turn out to 1.5 turns out on the air screw. It seems to start just a tad easier and didn't load up at all in the tight stuff we were riding in.
I have my 38mm PJ chucked up in the lathe and I'm going to experiment with some different bell angles and tapers, then machine a 36mm stuffer for the carb outlet.
I also machined some of the impossible to find, rear fender collars, out of aluminum. They turned out really nice. One of the beauties of the small Chinese lathe is their ability to make some very small intricate parts.

In light of my normal depression after another Blues playoff lose (it's a yearly thing) I decided to work on the CR.
To the delight of most, I ditched all pink accents and went with the more traditional "Works" disc cover, new oem fork boots, red number plate, correct 250 number plate decals, new shroud decals and Pro-Link decals. I also put a new set of Ricky Johnson Renthal CR Hi-Bends with new grips and levers.
The rear subframe was bent, broken, welded, and bent some more. I picked up a clean specimen from eBay and ned it for the time being.
I installed the Onformula1 lower subframe bolts and machined some more collars for the exhaust hangers.
