Well, when I got my car two years ago, Rich Roback did the PPI and told me the Borla had a rattle-but it had no external problems. Today I noticed that it now has a nice even 3-4" crack in the weld along the top left side. So, I need to contact someone at Borla to find out what they are willing to do about it. Unfortunately I'm not the original owner and don't have the receipt .....
I like the muffler (nice and quiet at highway speeds, good sound accelerating), but depending, I might go to an X-pipe to reduce heat and weight.
We'll see next week what I learn about replacing it. Does anyone know who to call?
