So I finally got around to seeing what the car sounds like truly straight-piped. Since the Capristo mufflers is clamped only about a foot backward, it was easy to remove the whole thing and drive around. Volume gained another 30% or so and you can definitely FEEL the rumble a lot more, without undue drone. However you're not going to get Hellcat volume or even the volume I had with my (almost straight-piped) E63. I think it's a combination of the smaller displacement engine along with the turbos and cats. Nevertheless I dig the improvement so I'm going to have my exhaust guy make straight pipe sections that just clamp onto where Capristo muffler was.
If you like loud, I can wholeheartedly endorse saving thousands on the cost of a custom exhaust and just replacing the OEM muffler with straights. (Per above, there is no OEM crossover or resonator section at all before the muffler, so it will be completely straight back to the cats.)

AMG GLC 63s Coupe
Yeah, the color is definitely something unique. I'd say it's 70% red and 30% burnt orange, and I love orange. One of the tragedies of the modern auto industry is the proliferation of boring colors -- do we really need 500 variations of grey? I was actually reasonably close to buying a Hellcat or Mustang simply because I could get a crazy color on it.... I wonder if Mercedes offers "individual" colors like BMW does. Might have to look into that in three years... would love a Plum Crazy AMG.

This is likely a stupid question and frankly, I have never kept a car past the 1 and 1/2 year mark so I know nothing about inspections.....but...can you remove the OEM muffler and replace with straights and still pass inspection? Probably varies by State but if it helps, I am in TX.

CATs? Not myself since I'd never do that but I've heard such shops exist and will do the work with a personal introduction. I'd suggest showing up to car meets and asking around. (I don't know if you're on the AMG NorCal Lounge Facebook but there is a big meet happening on Feb 8th in SLO.)

Check Engine Lights?
If you guys want the the most sound and performance I would go the route I took.
1. Buy SSR Downpipes.
2. Custom fabricate Vibrant 7830 High Flow Cats onto downpipes.
3. Install.
Out the door with install it is $2500. Paired with the performance exhaust is great. Sounds decent with the valves closed for around town but when you open it up it sounds like a sceaming banshee.
Also the cats added in really make the sound of the car more refined. Takes away that raspy with the decatted downpipes you hear online in videos. Most importantly the gasoline fumes smell is tamed.
Ill try and get some videos for you guys.
Cheers.

1. Won't it cause check engine lights and all other sorts of problems?
2. Will it actually pass inspection? I'm in New York.
I'm waiting on receiving my 2021 GLC63 and after breaking it in properly, I'm going to want to enhance the volume of the sound. I just want it to rumble without having to drive like a lunatic.
I guess what's the least disruptive way to achieve that?

After googling, I'm seeing that a muffler delete can result in the car not running properly due to the fuel injectors and speed of air flow causing all sorts of software issues.
I'm waiting on my brand new GLC63 and was looking at deleting the muffler to here the rumble. I don't care so much about pops and bangs, I just want too hear a loud rumble.

Have you gotten check engine lights since the muffler delete?
