I saw a thread regarding the stock 335i muffler being cut open to be welded and gave me this idea. I thought it would be neat to keep the stock muffler sound level, but just mod the "flapped" portion of the exhaust canister so that it was louder only with the flap open, in sport mode or at higher throttle levels. Sort of a "have my fun, and not piss of my wife and neighbors" situation.

Has anyone tried this?
