Thanks for sharing Magna_Flow!
We've installed your muffler on a couple different E46 M3s and it's always been one of our favorites in regards to volume, tone, low drone, and power! Two of highest NA power'ed E46 M3s ran your exhaust.
My only quick suggestion, never jack the rear of the car from the differential cover. There is an increased risk of damage. Just a couple inches in front of where the rear was jacked in those photos, is the rear subframe carrier. I highly recommend jacking the car from there where the flat spot is.
Awesome work with all your exhaust systems!
