Thanks for the good information. I'm a car guy, but I'm not too good on how the BMW exhaust system works yet. Can you explain it to me or point me in the right direction to learn about it? (DPF, DEF, layout, etc) So you think even if we changed the mufflers, it wouldn't produce any more power?
For the K&N filter, what are your impressions of it? Sound, power?
A FMIC would be awesome! Just need to modify the front bumper then. Did wagner say how long it would take them?
