I have a flowmaster 40 series muffler that came off of a GTO for sale. It already has a tip welded on it. I had 2 of them but welded the other one on my truck. I also have a spare tip if you want it. Fits great and sounds great too! It is in great condition. Asking $75 for it locally or you pay for shipping.
I also have the stock muffler off of my 2007 trd sport
