Replaced a shot muffler with a new cheapie from Autozone. A few minutes with the sawzall to remove the old one, quick shot with a cutoff wheel to remove the remaining bits from the pipes, one false start at fitting the new muffler - outlet tube a bit too long, so back to the sawzall - and bob's yer uncle. Not really worth taking pictures. I was surprised at how easily the old stuff came apart. I was worried I'd be under there cutting and hacking and hammering for hours.
