db rating for M Perfromance silencer for m135i
Hi All,
I was wondering if anyone could help. I take delivery of my m135i in December and i am unsure about fitting the M Performance silencer. I like to do about 3 to 4 track days a year and some of the tracks i go to are very restrictive on DB levels. Does anyone know the DB levels for the standard silencer and the M Performance version? I have had a look around but not had much luck in finding any technical data. And the parts department at the two dealers I spoke to have not got a clue. in fact one guy was so unhelpful anyone would have though I have asked him for the chemical formula to turn lead into gold! Anyway, if anyone could help that would be great as i don't want to be asked to leave any trackdays because i opted for the M Performance option. Cheers D |

I think the noise level is mentioned in the car documents in Germany, so anyone with a standard, German M135i should be able to answer that part. A little bit more difficult with addon parts, but there is probably some TÜV-papers for it. Maybe search for "gutachten".
