Arrow Dual Canisters' Db Killer Removal

My Arrow dual canisters came yesterday. This morning I attempted to remove the Db killers. They are held in place by both a large snap ring as well as a small weld. Obviously, they were not going to make this easy like Akrapovic does where you only have to remove a small bolt and you're done. So, I got the snap rings out which was not easy because the there was a piece of welded steel there to prevent their removal. However, the Db killers still won't come out because of this weld. So my question is: Did you guys break or cut the weld? Did you use a dremel tool or what?

Thanks.

Yes, weld needs to be removed. Just a small tap with a sharp carpenter's chisel is enough. The weld is very loose and symbolic at best.
Weld is there so the cans conform with EU regulations (eg. the noise baffles are a "permanent & non-removable" part of the cans).

I'm surprised you managed to remove the circlips with welds in place. They must be well mangled & bent now, eh?

Yeah, the circlips are bent--didn't figure I would need them! So a small tap of a chisel does it? Gee, I shoud have posted up first because it sure would have made removing those circlips a lot easier!

Thanks for the quick reply and advice.

Dremel with cutting wheel to cut the welded tab. After that use grinding tip to smooth out any remains of the weld - restrictors are very tight fit, weld left on the rim will prevent them from sliding out. Squirt of PB Blaster around the edge helps with pull.

Edit: mine were small tabs pretty securely welded there, I don't think that chisel would cut through them...

Yes, those are the ones. One tap of chisel and the tab and weld flew out. Might also work if you just sneeze at the offending part. Maybe a little sandpaper to clean the leftovers, can't remember anymore as it's been a few years.
The welds appear to be different now--was unable to dislodge them with chisel and hammer. Looks like I'm going to have to cut the suckers out of there...What a PIA!
