Mercedes C450 AMG sound upgrade
I live in California (if anyone knows a guy here) and own a 2016 C450 AMG, and I was looking to upgrade the way the car sounds. I was recommended two options by two separate people and I want to get a different opinion on what to go with. I was recommended the following options:
1. Axel back (don't like this option)
2. Secondary cat delete
3. Secondary cat delete + resonator delete
What should I go with if anything?
Thank you
