Hi everyone,
I bought this car a couple years ago and now I want to hear more aggressive sound from the exhaust.
I'm not sure which parts should I get for my car. Can you please help me finding the right parts for me?

Well with the c63 world it usually comes down to deleting parts off the exhaust to make them sound better . But for real , I would start with a simple secondary cat delete and if that's not enough delete the res those both play alot in making the sound alot more aggressive.

Just keep in mind some states are strict on emissions testing and will not pass you if you delete sec cat

Definitely delete the 2nd cat first and see what you think. It makes a noticeable difference and sounds great (inexpensive too). There's no sensors in the 2nd cat, so AFAIK it shouldn't have any bearing on emissions testing.

BTW, this has been discussed many times. A search will produce a ton of useful treads on the topic.
