I chopped and cored the stockers (620 cans) to put on my 695:
Remove the cans and the mounting bracket screws. Then slide the sleeve down with some force as they are tight. Because of the pipe
angle where it connects to the header, you can't take off the sleeve. That is the really bad part about it because you have to work with the sleeve only part-way slipped down.
You will notice that there are welds holding the cap in place. The welds were the most difficult part for me on this project. I worked the welds before cutting off the end (I chopped 3" off the can) so I had something to hold. After cutting the welds as deep as I could with a Dremel, I took a flat screwdirver and started gently prying all around. As I worked the caps this way, I was able to Dremel deeper. When I thought I had cut as far as I could with the Dremel, I used a hammer and the flat screwdriver to knock off the cap the rest of the way. I was careful not to bend the cap too much.
As far as cutting the sleeve, I chopped mine about 3". So, after I got the cap off, I put the sleeve back in place and bolted the hanger back on as a keeper. I then used a miter saw to cut through the entire can (multi-purpose blade). I suggest also clamping the can before sawing as mine moved a little even though I put some serious pressure on it while cutting. After I cut through the works, I did Dremel the outlet pipe back some into the can (about 1").
After all that, I put the cap back on, slid the sleeve back in place, and I then drilled three holes (they hit about the middle of where the cap slips over the can)--top, back, bottom. The holes were big enough for the rivets I used. After drilling, I riveted it together. So, the rivets went through the sleeve, cap, and can, The sleeve circumference does not allow you to rivet the cap under the sleeve; they will not go
back into place.
