After having it looked at by 2 local shops, I took it to Exhaust Pros today and finally got the scoop, maybe. They said that while towing I burnt out the packing inside the Borla due to overheating. They also said this can happen with a V6 and almost never does with a V8 as it will stay much cooler under load.
If this is true, I feel like I would have read something about it (burnt packing while towing) from at least one of the hundreds of T4R owners running a Borla on this forum. But I never did....
Anyway, the Walker Quiet Flow seems great so far (maybe 15 miles in) so it seems I'm done with the exhaust headache, but still curious about damn Borla...
Anyone have a similar issue after towing?

Did you attempt to contact Borla at all for a replacement?
