dandandan Another way to reduce drone is to lay down some dyna-matt sound deadening under the trunk liner floor - in and around the com/mulf box area. A lot of 1M owners did this to reduce drone... and it should also work for any 135i driver too. I remember one 1M onwer who used a small pillow to reduce the noise coming thru the trunk floor area!!

For me... the PE makes my 135i sound so special. I love the sound! LOVE, LOVE, LOVE that music that comes out of exhaust. I still get complements on my exhaust. But I have a manual and a N54. I friend of mine with a N55 dct has a 200 cell AR high flow cat... with his stock exhaust and damn does his car sound great coming out of the hair pin turns in the Alps on your Alpine adventures.

I've only gotten one negative comment from a non-car guy at my work... he always asks me when I'm gonna get that hole in my exhaust fixed... and I just chuckle.
