Just did this today. Amazing. Easy. No error code, instantaneous better sound, eliminates flatulent cold-start. Best part... its reversible, however should be required by all M3/M4 owners!

I cut the fingertips off of a Nitrile glove and covered the plug (home-made condom for the plug), tie-wrapped to secure, and then taped the female receptacle with electrical tape.

Viola! No need to get an exhaust system... maybe down-pipes though!

Thanks a million for this thread!

Newb!
