muffler fell off!
ive had an exhaust leak for a few months now, corrosion that broke through at the exhaust hangar about 1 foot in front of the muffler, been nothing more than a nice 2 inch hole or so until yesterday on the way from san antonio to corpus christi, i was driving about 65 with my son in the front seat and all of a sudden...
huge dragging metal noise, didnt know what the hell it was, so i pulled over off I-37S looked under my truck and bam there it was. That exhaust leak i had broke through and the muffler nose dived. thank god that I had a mini sledge on me and a knife so i just cut one exhaust hangar off (the bolt ladder looking kind with a piece of rubber between them) i cut it through the rubber obviously, and the other hangar was the typical "hangar" once i cut the other one and knocked it loose with the sledge, i just slid it off the "L" rod and threw it in the bed of my truck (took about 15 minutes) thank god my father helped me recharge my A/C the day before or my son would have been roasting in my truck while i was doing that...
moral of the story???
fix your damn exhaust leak when it happens!
my dad aint gonna leave me alone now lol

finally got it fixed guys
went to a local muffler shop and got a new flowmaster "10" series, took less than an hour heres some pics...
welding seemed very nice, and they triple checked for leaks everywhere
however i noticed that when they dumped it it was dumped literally about 4 inches in front of the axle and was practically dumping all the exhaust onto the axle, so i asked them about it 2 days later if it was safe or not, and the owner checked it out, i was asked for his honest opinion if i should worry about my axle heating up where it dumps, and he said it did seem pretty close, so he took my truck popped in right in the shop, and took about 6 inches of the main pipe, no charge, great service, heres an updated picture, i know you really cant tell but it does seem better to me
the muffler is very smooth on my engine and i love the sound, nothing too crazy, although it is a "10" series, it is on a V-6 remember, I think it is a great sound for me, not harsh at all and resembles the rumble of a V-8 at idle (my optimistic thinking )

Glad you got it fixed. Everything is still intact under my '01 but I am starting to think about putting a new muffler in it, a lot like the new one you just got installed. I am looking for both improved air flow and some sound. I have lost count as to how many times several of my friends have commented on how quiet my truck is and it's a V-8!Clint (TX) 2001 Silverado LS 4.8L auto 2wd ECSB [GARAGE]

Speaking of exhausts, does anyone know the diameter of the stock exhaust tubing for 2001 Silverado? I am about to buy a Flowmaster muffler and Amazon insists that it is 3" but I went out and measured my tubing. I swear it's 2.5".

That muffler looked a bit ashy in color no? Maybe just the pics?
