Actually, I am the 3rd owner of my car and the Ford Racing muffler cracked along the upper left hand edge. Borla replaced it free (including shipping), even though I had no receipt and was not the original purchaser. I posted a message about it a few days ago. List price is now $2750, I believe.
I got a free replacement (not including installation) as the 2nd owner. I didn't tell Borla that. I just took some photos of the cracked weld and asked for advice. They sent me the last Ford Racing branded muffler in their inventory. The mufflers are now branded "Borla," because FRPP no longer sells them.
