from past experience the problem with them is where the system joins to the down pipe , they never clamp up well and end up working lose , nothing a welder wont fix though

another option is to have a word with a independent powerflow dealer and ask if they will make you a stainless system for similar money if you put some of their stickers on your car , i did the same with with one that had not long started doing them and was looking for advertisement , peeled off the stickers a few days later
