Few problems…

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?
I just spoke with Dinan on the phone about the cutting. They stated that they follow BMW's exact specifications on mufflers. What that means is if BMW had to send you a replacement muffler there is a section on your old muffler that is marked where you would have to just cut it off and attach the new one.

So yes this exhaust requires you to just make one cut on your existing one and then attach the Dinan exhaust to it with the clamps provided. They stated it was done like this because these are BMW's directly guidelines on replacing a muffler.
