[ocarioca1m]

The M performance exhaust is no ricer exhaust. No M3 or M5 exhaust either. Does have a nice tone to it on acceleration. You can tell it is different. But still you can hardly hear it inside the car. My 1M used to set off the alarm of my second car when started up. My 335i with M performance exhaust and catted downpipe just doesn't. I'm thinking of switching to the dinan exhaust.
