Hey guys, I recently purchased a 2019 C43, unfortunately it came with the stock exhaust. I’m new to the car world so this may sound a little dumb but how difficult would it be to swap the stock exhaust to the AMG performance exhaust? Also, any recommendations on where I could purchase one for a fair price? Thank you!

Lots of threads on here
most will prob say it’s difficult and print not worth doing oem PE. Get new aftermarket AWE & FI I think r the ones I’ve seen

Ive had both of these aftermarket exhaust options and they still don't come close in sound to the PE exhaust on their own.

AWE touring exhaust - forget it. its too quiet. Similar to stock to be honest.
FI exhaust - is maybe 5-8% louder than the AWE when you get on it, still in the quiet sound range everywhere else while daily driving.
FI exhaust + logos catted downpipes - got 20% louder - I actually like this setup and i'd say its now comparable to the PE.

The PE is by far the best, even if based solely on the fact that it is integrated with Mercedes own infotainment. Having the valves open and close with the mode changes is extremely convenient.

Looks like I responded to the wrong thread. I meant to post the below here.

Related threads (feature) can work against us sometimes but I do find them useful other times.

I could not disagree more. My FI exhaust was significantly a louder than a stock PE. After downpipes it is criminally loud.

I wonder if it has to do with differences with PFL vs FL?

The closest one to an actual PE (heard them all) would be the Logos exhaust. It's delicious and has that PE tone.

I think they are the forum sponsor too.

Do you by chance have a 2019 C43 with the Logos exhaust? I really want to get this one but I have a lot of questions before purchasing, maybe unneccessary but I don't want to waste time and more importantly money. These are my concerns:

1) After physically looking under the car and hunting down the OEM underbody diagram on the Mercedes Benz parts for sale website, it looks like the stock midpipe is a single straight. I hope I'm wrong and from others' experiences I probably am, but doesn't this mean the underbody frame is fitted for a single midpipe, thus an H-pipe with 2 parallel pipes would not fit in this frame without causing wear and heat damage to other parts right?
2) Are the Logos front pipes compatible with the stock cats/downpipes, meaning no cutting or welding needed for fitment?
3) Do the Logos mufflers fit exactly to the fake exhaust tips/ports in the stock diffuser? Or do they need to be cut/welded or even removed for the Logos mufflers to fit?
4) I do not have the AMG performance exhaust so do the Logos valves need to be wired to the trunk fuse box for power? Is this an easy install?
5) With the Logos exhaust kit (not including the high flow cats and downpipes), if I add the Logos cold air intake, would that tip the scales in air/fuel ratio and require a tune?
6) I don't know if my stock exhaust has the OPF, but if it does, does the Logos exhaust replace this or no? And if not then wouldn't that throw the CEL and require a tune?

Sorry, I know nothing. Please help. I also have images of my car's actual underbody (from rear muffler angle only) and the OEM diagram I referred to. I can share them for clarity
