Firee im going to do the same to my 340i since it’s technically the same. You think it’ll have a lot of drone if i weld the little tube to the second chamber to get the loudest sound possible? Or would it just add drone no loudness wot?
I would just weld shut the perforated holes. If you want more noise remove the resonator in the middle section of the exhaust and program your valve to stay open 100% and you’ll get what you want for a fraction of the cost of an brand exhaust.
nice sound lovely sound raily better than the m4 f80
