You’re welcome. Interesting to see that the Brombacher and Dansk do have different internal designs.

Here’re the weights for the three mufflers I have in hand. All weighed with our trusty electronic luggage scale which has proven reasonably accurate across the years.

- Borla: 19.7 lbs (with welded c pipes to connect to cats and welded bracket - ready to install, no additional parts required except cat pipe clamps). To note, the Borla welded bracket bolts directly to the transmission, so there are a few lbs of additional savings because the heavy Porsche transmission bracket and muffler top bracket/isolators are deleted. Mounted, the Borla is easily 10 lbs lighter than stock.
- Brombacher: 24.5 lbs (without top bracket/isolators, clamps or c pipes)
- Stock 550 SE: 27.4 lbs (without exhaust tip, top bracket/isolators, clamps or c pipes)

So, installed, the Brombacher is ~4-5 lbs lighter than stock w/tip and it is ~5-7 lbs heavier than the Borla according to my measurements. YMMV.
