DIY C55 Resonator and 2nd cat delete!
Just sharing what I did this past weekend on my 4 month old used 2005 C55 via video. Slapped all the stainless steel parts together and had local shop do final welding. Nothing too wild just mild. Already have a massaged 5.0L to make me deaf. Overall, I'm very happy with the tone and end results with this daily driver!
