I am currently at a crossroads in my Black ownership. I purchased the vehicle late 2013 with close to 6,000 miles from the original owner (currently has 30,000 miles). Shortly afterwards, I had the secondary cat and resonator removed and straight piped since the exhaust was not loud enough for my taste. Though the sound was amazing at the higher RPMs, I still disliked the raspy note at the lower RPMs, so went ahead last week and had it reinstalled back to factory. Wow! Didn't realize how much deeper the signature AMG growl is but feel like I can barely hear the exhaust note!

My car is completely stock with the exception of exterior enhancements (carbon fiber front splitter and side mirrors, xpel ultimate paint protection, radar detector, etc.). That being said, I am currently debating either of the following:

a. Keep my Black and install long tube headers and mid-pipe ($3500), throttle blip ($2500), and ECU tune ($1000).
b. Put my Black on the market as is and purchase a used W205 C63S Coupe ($65K). Will likely get a downpipe and ECU tune ($3000) in the near future.

I currently have a daily driver (G37S sedan) so this will be more of a weekend car. I plan to drive the C63S coupe soon but any thoughts/opinions?

Though the Black should have better handling (one of the main reasons why I went with a Black Series over a "normal" AMG), I would think the C63S has a slight edge with much better transmission/shifting, ability to dynamically change suspension, throttle, and steering settings, and no possible head-bolt or camshaft issues to worry about.

Can someone please fix thread topic to W205 C63S coupe? Thanks.

If I were to buy a W205 C63S, I'd daily it.

CLK63 BS, I'd keep it for special occasions or weekends.

So it depends on what you really want.

My BS has the EvoSport LTH and X pipe with dual resonators. The car screams when opened up, and still fairly understated when not driven hard. The sound is pretty deep in the lower RPMs. No drone what so ever while cruising. The new AMGs do sound pretty good. But they sound different due to turbocharging. I guess it all depends on your preference.

Thanks for the responses. Here are some pics taken at 27000 miles after just being washed/waxed. The entire front section (hood, bumper, side fenders, splitter), side mirrors, door hinges, door openers, side skirts, rear's front fenders, rear bumper underside are all clear bra protected using xpel ultimate.

I am considering maybe leasing a C63S Coupe for six months to really gauge the differences since a test drive with a salesman won't really cut it. Unless they let me take it for a spin without anyone else inside (like they funny enough did when I test drove the Black for the first time and right when leaving the dealership the tail already starting coming out ).

If you want exclusivity keep the black. Around here C63S are a dime a dozen and depreciate quickly
