My MBRP, and a bunch of others have had hangers pull out. They have a 10 year warranty on the 304 and 409 stainless, and a 3 year on the aluminized. I have been moderately pleased with it, but honestly I will not buy it again. I recently put a Grand Rock muffler on my truck, and I am extremely pleased with it. While its not a complete system, I am happy with the QP muffler. I am not 100% sure about their full systems, but judging by the muffler, I have no doubt it will be great. Silverline also makes a very nice kit.
