a pain in my butt!!!
the muffler was a pain for both my 1100 and 2100. after beadblasting them i used an oxy/acetelyne welding tip to heat the braze they used to hold it all together. i pulled out the tubes for the mounting bolts and then the baffle in pieces. it was tough and i ended up cracking the thin metal the muffler shell is made of. however when i brazed the mounting bolt tubes back in i used brazing rod to fill in the cracks easy enough. then i used a die grinder with a carbide bit to shape the opening for the outlet tube(tubes on the 2100) and brazed on the pipes. then i reblasted them to clean them up and painted them with a muffler black paint. i think they were worth it because these engines like to pump their air and both run well with them. last time i used my 1100(the tree the video on youtube is on) the exhaust was blowing bark off the log when i was bucked up on them. i haven't seen a muffler up close where it exhausts out the lower front of the shell so i dont know what they look like internally but these older mufflers i have were a pain in the baffle area.
