SL55/63/65/R230 AMG: Secondary Cats and Resonators Removed (VIDEO CONTENT)
So I have removed both my secondary Cats and Resonators to get a bit of better sound out of my SL55. On the Diagram what was removed was 158 and 159. This was replaced by 3 inch stainless steal piping with some good welding done. I gotta say this is a huge improvement over stock. There is no drone or check engine lights on in the car after this removal.

I think all together with the piping that the shop covered it was around $200
Thank You! LOVIN IT.
