Not all that long ago, one of the dudes I work with had his new axle-back Borla's stolen right out from under his car. He was at a sporting event and they took the whole damned thing. Well, he's got it replaced now and took it to an exhaust shop JUST to have them put some spot welds on the areas where the exhaust comes apart. If you've not done something so keep them secure then you need to. If you have, what was the method you used?
