hardly any sound from the exhuast
hi guys, my buddy and i both owns a 1m in china and the question is, we can hardly hear the exhuast sound on both our rides. from the clips from you tube, both the engine n exhuast sounds great so i wonder if bmw offer a different settings or some sort to lower the sound it makes to meet the import standard. pls share yr thoughts with me, tks

the sound coming out from the exhaust pipes in the stock china 1m is hardly noticable unlike the 1m from the US or anywhere else. my buddy noticed the same thing so we are wondering if the china version 1m exhaust system is different to other countries

Search the forums. It was discovered that 2 of the 4 exhaust outlets are blocked off on Chinese-spec 1M's. A forum member even went so far as to cut open his exhaust to show it. It must be for noise purposes as it would have no affect on emissions.

oh yes i remember seeing that post but didnt know it was referring to the china 1m. what also seems weird is that other stock supercars in china are loud as hell so i really dont understand why bmw had to block 2 of the pipes. is there anyway unblocking them? tks

It seems to be a spec for the Chinese market (likely for emissions or noise reasons):
