Just got back from the muffler shop. I explained the situation to the owner and he was actually pretty rude. He scoffed that the pipes must be all misaligned and out of whack if we got it to go together. I told him that is not the case at all, fitment is perfect and he is more than welcome to put the truck on the lift and have a look. He then pulled a *** of money from his pocket, peeled off 3 $20 bills, threw them on the counter and walked away.
I bid him a good day and walked out.
I was actually only going to ask for a partial refund, which I thought was fair, but with the attitude I received I decided to take the full amount. See ya!
