Going to have the stock exhaust ripped out replacing from the secondary cat all the way back with an xpipe and new mufflers. I'm not looking to go loud, just something aggresive. the perfect sound is my amg which is a low deep growl that screams when you hit it but quiet when you're cruising.Now my muffler options right now are going with stock m6, stock f10 m5, or this new dynamax muffler that claims to eliminate drone.

anyone have any experiences or insight to which would be better ?
