The GT Guys discovered this. I've been getting a tinny/buzzy sound (like a loose baffle might cause) at about 2k rpm. I wonder if this is the cause or if something else may be loose inside.
Cracked weld on FRPP muffler

The Borla should have a million mile "lifetime" warranty to the original owner. Do a search you will find some photos on one that failed inside. 911teo I think posted them. I just got a new one and my understanding is they modified the muffler to address the cracked welds. I hope that is the case.

I sent an email to Borla with the photo. We'll see what they have to say. Sinovac knows a great welder in our area. I'm wondering if it's worth cutting the box open, stuffing it with steel wool and rewelding. Or maybe just hang it in the garage and get an x-pipe. Sinovac already has me mesmerized with his headers and polished Borla though...so if I go that way, keeping the Borla would be nice.

Same thing happened to me about three years ago. I had all external welds redone by an stainless welding shop. They said the factory welds were pretty, but shallow. They rewelded all my external welds and they look wide and deep. I have had no indication of internal problems, so don't give up on the muffler until you reweld the externals. Borla told me they would be happy to fix the problem if I had the original receipt (I didn't) and I mailed the 40 lb muffler to them! The rewelding was very affordable. Bottom line: I love my Borla.

Where/who/when did you get the muffler from, Gary? If you're the second owner, you may be SOL with Borla. From what I understand, as Clinton mentioned, this was mostly an problem with older mufflers. But they seem to be quite receptive if you're the original owner and have had weld issues.
Ed, I got the muffler used on an eBay auction. I was the only bidder, so I got it for the reserve...$1,400. Can't blame the seller...it was fine when I got it.

I would still give Borla a call to see what it would cost to have them repair/rebuild it to current specs.
If the problem is only that one external seem, then having a local guy TIG weld shouldn't be too costly and with the right shielding maybe it can be done in place. LOTS of shielding! However another weld could fail anywhere in the future so YMMV.

I'm sure it was fine when you received it. They're obviously known to fail by several members' accounts. Like Clinton said, doesn't hurt to contact Borla. Who knows, even if you are the second owner, maybe they'll still stand behind their product??

Before you cut the box open, I would re-weld the split seam first as Howard suggested. Unlike the OEM breadbox, the Borla muffler is easy enough to remove from the car if this repair didn't work. I would be happy to help you.

Gary,
Borla has confirmed a direct correlation between this failure and passing over a double line.

Also caused by driving over cattle guards at speed. :biggrin
All I'm gonna say is, if you have a problem with your Borla, give them a call.
I can't wait to take Sinovac up on his offer to shine my can.
