I have a stock 2007 BMW Z4 M Coupe, and decided to improve the sound, she’s a bit quiet stock. Picked up a DKF Section 1 (that comes with interchangeable resonators or 300cel cats). Of course, went with the resonators. Also picked up a set of Stromung mufflers.

Took them to Paddock Imports, where I help out with their social media. Shawn got to work, putting the car on the lift, and started by removing the OEM mufflers. Old stuff came off pretty easily, and the new stuff installed pretty well. Won’t bore you with narrative, it sounds good and I’m happy. This is how it should have left the factory. Here’s some happy snaps and a vid.
