Something is very wrong. Even my first - and weakest - exhausts lasted 500 kms. (full recap, up to January,
HERE )
I don't know what to say. My "mariocp" or "Car #33 edition" exhausts are still mounted on the car, since January have made another 1000 kms (not using the M3W as much as I should lately) and still not showing signs of cracking.
