Well today I was driving my 78 Chevy pickup. The muffler that was on it was all rusted out and the truck was a little noisy when driving. Anyway while driving the truck got louder all of the sudden. I knew that something happened with the muffler. I proceeded to drive another mile up the road to a parking lot but of course just before I got there the large 2.5 foot round muffler fell off almost catching the motorist behind me by surprise. They managed to avoid my muffler. The muffler had a good run since I bought the truck in 2012 with a rusty muffler. I patched it once with some sheet metal and a welder. It lasted for a year or so which is ok living in the rust belt. Anyway I picked up a new stainless steel walker quietflow from advance auto. The muffler was $99.99 so I had to add .99 nail clippers to get the order to $100 so I then could use the code TFT41 to get $40 off. On top of that walker has a $30 prepaid visa mail in rebate. So the $100 stainless steel muffler came out to around $35. Works for me with a lifetime warranty. Pic of my old muffler below.
