I think there is a problem... just spoke to my local BMW guru and thus is what he said...
Dinan uses 20g stainless. WAY too thin. Great for lightweight, but terrible for TIG welding brackets to it, as the heat from welding and use will crack the steel. Even in our exhaust, we only use 16g stainless for strength.
Dinan’s version is a “cut off” muffler, which means you have to CUT your stock exhaust. This is ridiculous. The factory muffler can be removed with tools! Dinan was too lazy (or too cheap) to make the exhaust longer to make it bolt to the factory location?
