The brackets are attached by a nut and bolt and are fully adjustable. You can rotate or slide them around as needed and then tighten the bolt. With the 19" turnouts, you don't really need the bracket, I took them off. The clamps that came with the mufflers were junk so I ended up using the stock muffler clamps.
