SL55/63/65/R230 AMG: CKS x-pipe installed
The x-pipe removes the secondary cats and the first set of resonators and the car sounds soooo much better!!!! Not as loud as I thought it would be given only the primary cats and the final resonators remain. With so much HP out of the box, it's really hard to say if I notice any SOP performance increase....

Will try and do a vid some time soon.
Here's a couple pics:
