GLC43 resonator delete results
 

I usually like a louder car than this. Does the resonator delete make it 10,20,50% louder? And more importantly....how bad is the drone in the car after it is removed! Thanks

DameMD I see you did the delete....how do you like the results?

It's loud no drone what's so ever. Especially now that the weather is colder, when I start the truck it's sounds bad a$$ and up-shifts (farts/backfires) are super loud. Now that I finally got the Mercedes ME app working properly on my both my phones, I will start the car from the app and record from one of my phones at a distance. Maybe tonight I can give you guys a video of the snaps and pops from the resonator delete from inside the truck and windows down. I don't have a GoPro so I need to see which one of my phones take a better Audio/Video: Note8 or Iphone 7Plus

Finally got around to doing it, i'm going tomorrow to get it cut and all done up. I can post my thoughts and possible videos if anybody is interested!

So how does it sound? clips? video?

Can you post a video of the resonator delete from the outside? Considering the same on my C43, thanks.

I believe the C43 exhaust is different in terms of muffler setup, however @justinspargo on instagram has a clip of the resonator delete on his page. I would record a video but do not have a gopro or anything close to get proper sound.

Are people with the standard exhaust usually doing the resonator delete?

Definitely interested in seeing this video.

Will this mess with your ability to pass inspection or is this resonator simply to muffle the exhaust note ??? In MA I ain't passing with no CAT's for instance.

I just recently got my '18 GLC 63 and did a resonator delete, and it sounds incredible. I didn't have the perf. exhaust prior, so I was seriously jealous of all the other great sounding AMG's, now mine sounds even better. There is barely a drone, and the engine sounds great, and it will still pass emissions!

Getting it tuned by Labworx in the next few weeks to get it up to 620whp and a burble tune, can't wait.

Cool glad to know it will pass emissions. Inspection stations up here in Ma are getting stricter and stricter by the day.

Hey Bluejae -

I have the regular exhaust and did the resonator delete. I bought my truck in April 2017 and the PE exhaust was not out at the time. With the resonator delete, there's no drone what so ever. You can change how the exhaust sounds by switching modes between Comfort and Sport+. In comfort mode its still quiet but you can tell the exhaust has been modified. In Sport+ it's nice and loud. I would say just a tad bit louder than PE equipped GLCs. I completely forgot that I have some videos up on a youtube channel if you want to hear it. https://www.youtube.com/channel/UCCB..._as=subscriber

I now have Mike's Customs Catless Downpipes that I sent off to get Ceramic Coating by Jet-hot.com. Once I get them back in about a week or so, I will install them and post some more videos.

Hey Dame - Would it be worth deleting the resonators if I already have the PE ?

Resonator delete will pass inspection. Its the Catless downpipes that will get you flagged.

Not sure. If you listen to my videos, I think the resonator delete on the "non-PE" GLCs sounds a little bit louder than PE. With that being said, PE with resonator delete will be probably be louder. The good thing is you can control the valves on the PE exhaust so you can make it quiet even in Sport+. Since the non-PE GLCs are 2 in-1 out from the resonator to a single 3 inch exhaust to the muffler, this probably explains why it's so much louder when removing the resonator. The PE exhaust is true dual piping 2.25in to the muffler. Idk if changing the resonator on the will make it a lot louder.

If I had a PE equipped GLC, I would still do resonator delete. I have done resonator delete with almost every car I had owned.

Watched/Listened to the videos and when you get on it its pretty loud. Sounds good though. How labor intensive is deleting the resonators?
Is it just taking out the material inside the resonator and/or does it involve cutting and welding back together?

ASR
 

I have PE and ordered the ASR solution. Hoping it will sound close to DameMD’s monster.

Please post vids when done. I really wish I had the option to mute my exhaust in instances where I am trying to sneak out or come home late :hammer:

How does the ASR change the sound of the exhaust ?? Thought it simply opened the valves (i.e. Sport + sound all the time) but didn't know it actually changed the PE sound at all. Maybe I am thinking of something else.

I just got my GLC63 with AMG PE exhaust and the first thing I did after getting home was crawl under the car looking for the resonator. I don't see anything resembling a resonator at all.. there is an h-pipe connection before the muffler but that's it. Does one simply not exist on this car? With my E63 I first went resonator to X-pipe, with no noticeable increase in volume, and only after I went X-pipe to straight did I see a huge increase. I don't think the same strategy applies here since even if I sever that H-pipe connection the muffler appears to be one big complex chamber, with all the valve mechanics inside. I have ordered the ASR system and will see what the does. My preference is usually for exhausts that wake the dead but I don't see that happening here without a full custom, which I'm not willing to do. Guess I may have to settle for just disturbing the dead...

I have seen GLC 63 pictures and I don't recall the middle resonator ,just an H or X pipe and direct line to the rear muffler . The 43 has a X pipe , a middle resonator and then pipe to the rear muffler .

I took another look and discovered a second H-pipe, near the front, with its own valve. Perusing threads leads me to believe its function is this:

"The standard exhaust has a valve further up near the subframe functioning as an "H" pipe. In comfort this is open, allowing exhaust gasses to flow between the dual pipes. In sport/+ and WOT this closes allowing straight through "dual" exhaust to flow through the system"

Of course that's talking about the 43 standard exhaust and not the 63 PE, but the description of that particular part seems to be the same. This seems to imply that if I cut the rear H-pipe too I'd get an additional volume increase, but perhaps I'd confuse and destabilize the actual PE muffler with its complex internals. Maybe best to leave well enough alone.

UPDATE:

In addition to the TWO h-pipes, there is a x-pipe between them. Didn't notice it before since the curves were somewhat subtle but it's there and definitely not a resonator. This is definitely a crazy Frankenstein of an exhaust.

Seen this post and thought I would share actual pictures of the GLC 43 exhaust without the performance exhaust. This is the stock system before I did the catless downpipes. No valves, and no X or H pipe set up. You get valves with the PE exhaust at the rear only on the 43.
Also, you guys are asking about sound after resonator delete? I can't help you there, as I did not do anything other than the downpipes but it is pretty loud. Much louder than I thought, and honestly, it sounds perfect at idle and WOT. I do have a video of it starting up with sound I will try to share. When it's started in the garage, it actually vibrates stuff throughout the house, and anytime I leave before the family in the morning, they get woke up. Last car I had that did that was my Supra, so I'm a bit impressed.
