GLC43 owners - help! '18 C43 owner considering switch

Current owner of an '18 C43 sedan that turned out to be a lemon.

I am considering two replacement options: 1) 2020 C43 or 2) '19 GLC43. The suspension damping is much better sorted on the GLC, so I'm leaning that way.

Dealer has a near-perfect spec in stock. I went to check it out today and realized it did NOT have the Performance Exhaust. I have the PE on my C43 and there's no way I would ever consider another C43 without one. With the trunk area closed off from the rest of the cabin, the extra volume afforded by the PE is invaluable.

My questions are as follows: 1) Is there anyone on here that has a GLC43 with no PE? How is the sound?

2) Less likely, but is there anyone that has switched from a C43 w/ PE to a GLC43 without one?

I did a search and dug up a few old threads, but the best thread was filled with posts from '17 and most of them were just discussing the architecture differences between the two options.

Thanks in advance.

I have a '17 GLC43. PE was not an option on this year for the vehicle. Not having the PE is the only part that I regret. The stock exhaust sounds good but there are very few crackles and pops and when they do appear they are very subdued.

I'ts pretty rare to get a replacement on a lemon. The manufacturer almost always performs a buy back.

I had an ‘18 GLC43 withOUT the PE. It sounds good and can generate pops/crackles/burbles, but mostly in Sport+. It’s not as pronounced or noisy compared to a PE equipped vehicle. See if you can find both at a dealer and compare. That said, if I were to do again, I would definitely get the PE.

We have a 19 without the PE because my wife hated the 21" wheels that came on the GLC. The PE only comes with the 21" wheel package here in Canada. We drove one with the PE before buying this one and yes it was awesome but not a deal breaker. The GLC63 that we buy in the future will have this forsure though.

RENNtech makes a module that allows you to open and close the flaps via a fob.
Its not cheap around 600 bucks and it’s a plug and play.

Do all of the factory exhaust have the flappers installed?

i believe they do .
Easy way to check it is put it in sport plus mode if the exhaust gets louder than it does have flaps.
Sport plus mode opens the flaps and adds the rev matching on down shifts and gives the snap crackle pops

Mine doesn't have the button inside though. I don't think the car changes sound going between the different modes.

There is no button it happens when you chance drive modes.
Put your car in Sport + mode

Do you have any experience with this module? I'm on their site and there's some conflicting info. Says it's a plug and play, but on the bottom it says it needs to be hard wired to the exhaust flaps?

I have a 2017 GLC43 without the optional AMG performance exhaust. Will this module work with my vehicle? Or only for the cars with the optional performance exhaust? I'd be stoked and would purchase if it works and the exhaust is always opened like in Sport+ mode.

It is rare. It's going to be a situation where I either accept a buyback and walk away or the dealer auctions the car and MB makes up the difference to allow me to get into a replacement.

Thank you for the honest feedback. Much appreciated. It has been a long, hard battle to get out of the C43. Had to endure nearly 30 consecutive days in the shop, on top of probably another 15 days in the calendar year. Really want to make sure I'm not "settling" on the replacement. I really admire the GLC43 and think it has some distinct advantages over the C43.

I use the PE on the C43 everyday, so it sounds like I might miss it on the GLC.

Thanks for the detailed feedback guys. Has definitely been helpful. Going to see if the dealer will let me drive the car for a day so I can really make an informed decision.

Interesting. With where I'm at in the process, it'll probably be easier for me to just find a car equipped with the PE. Thanks for the info. though!

I just looked under my 19 GCL43 without the performance exhaust and there isn't any valves that I can see.

No performance exhaust = no valves. This has been covered already and if you search the forum you can see plenty of images of the stock exhaust systems that prove this. A valve has to actually divert somewhere and bypass around the muffler. The car will get louder and rev higher in S and S+. This is all ECU mapping, no magic valves.

I ordered my 2018 GLC43 with the performance exhaust (includes 21 inch wheels). Do I use it all the time? No but I use it when I want to and love that I have the option. I cannot say what it is like without the PE option but the PE is certainly way louder (and interesting) than when the PE is not turned on. If you like the sound...get the PE.

Get PE. I really think it should be standard on an AMG since why would you NOT want it on an AMG.

I do NOT think the renntech module will work with a nonPE vehicle because there aren’t flaps on them. Additionally I’d save $$$ and get the ASR module. I’m happy with mine but will likely pass through Toronto next summer to have MBhouse do some mods including the burble tune.

if anyone knows a MBhouse type place in the midwest, let me know. They seems to the 💣.

it won’t work with a nonPE vehicle I believe because there are no flaps on a non PE version?

Also I use the ASR which does the same for 1/2 $$.
