There's a good amount of Borla catback-only videos out there:

I have a Borla catback and I think it sounds great and no issues here either. It's also one of the lighter catbacks out there, around 26-28 lbs. Most of the dual tip catbacks weigh over 30 lbs, some almost to 40. I'm not sure why the Borla isn't more popular...
The UEL Borla header business, while it sucks that some of the products wasn't perfect out of the box, it proved Borla's excellent customer service plus their ability to uphold their warranty. I think they already helped out all the Borla UELs that had issues.
