I just put on an axle back version and it sounds great, not too loud but a lot more grunt than stock. Unfortunately, there are some fitment problems with the tips. I took it to a local shop to confirm that everything is lined up and installed correctly and they agreed that the passenger side tip is just too long. I contacted Meisterschaft earlier today but haven't heard back. Since it's just clamped on I'm assuming they'll swap out the pipe/tip for one that is the proper length and all will be well.
Here's a couple pics. Notice the passenger side sticks out about a solid inch past the bumper and the driver side is flush.
