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.)

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.

I plan on keeping this car!!!!!!!!!!!!!

1. Buy SSR 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.

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.
