Well, first off it's never going to sound like a C63. You have a 6 cylinder they have a huge V8. Can you get the volume, yes. Search muffler delete, magnaflow X pipe or resonator delete. There are a bunch of threads on the topic. It's really all about how loud you want it. Youtube must have 2 dozen videos. Type in C300 exhaust into youtube.

Outside of a custom built air intake there is nothing available in the market. Search custom intake on the W204 home page and you will see some results. Not done as often as exhaust.
if you want to go faster then you can do a tune. Again search is your friend. There is a huge thread on tuning and there was even a group buy for them. Keep in mind that doing a custom tune could void your warranty if the manufacturer determines it was the cause of a failure. Not easy to do but does give them an out.

As far as doing some of your own work see the stickys at the top of the W204 home page with a bunch of great DIY articles.

I strongly recommend you read the first 4-5 pages of this forum. Every thread has some sort of useful information. Lots of folks on here like to tinker with their cars, myself included. Welcome to the club and look forward to seeing a pic of your car.

Eurocharged ECU tune and 2nd cat delete and replace resonator with x-pipe and you're golden.

Maybe clear side markers and 35% tint while you're at it.

If I remove secondary cats and replace the resonator with a magnaflow 2.25 X pipe, would that make the engine light turn on?

No, because there's no O2 sensor after the 2nd cats. The 2nd cats don't even have catalytic material in there. It's a misnomer, and people only refer to it as 2nd cats on these forums because of it's location and possibly the way it looks.
