This is one seriously entertaining thread. The "fat persian kid" part had me LOL.
Of course there are 2 sides to every story. I am convinced based on the evidence posted thus far that the seller is 100% credible and the buyer here is 100% a spoiled brat.
There is no way anyone would pay for and accept an OEM exhaust with no visible weld marks etc. That is just crazy. I am sure the seller said something to that effect in a fit of rage just to piss the annoying buyer off. But we all know it was not the truth.
Let's have the buyer admit he is in the wrong and end this saga.... Great fun!
Time to make more POPCORN!!
