Dolmar 7910 and makita 6800i MM?

[MS460WOODCHUCK]

Ok guys I got the 7910 muffler uncrimped and apart. I know I need to cut the chamber off but what about the part of it that goes into the cylinder? Do you guys leave it? And then the flange that is in between the back of the muffler and the tubes the mounting screws go through. There will be a gap and the mounting screws won't be tight. Also what kind off mod do you guys suggest as far as enlarging the original port or make a second port?

Anybody with info on what they did?

Gut it and put the tubes for the bolts back.

The tubes stay mounted when muffler is pulled apart. The tubes are not long enough when the chamber is removed because the bracket/flange that holds the chamber in place which is mounted to the chamber and the neck that goes into the port is roughly 3/16" thick.

ADD pics if you can.

I'm going to mm my 6401 bb soon . The paint can opener is a good idea. Thanks

Just have to leave the flange between the tubes for the bolts and the back of the muffler.

I did it somehow and didn't leave any of the SLR stuff

Then there would be a void between the front and back of the muffler

Whatever i did kept the tubes and the piece at the flange there for support. I guess if I took pictures I coukd go back and look
