Good morning, G'Day, Good evening, which ever may be the case...new member here. Stalking is not quite the word I would use prior to joining the forum yet it would not be too far off the mark, if anything just to be sure this site was worth the effort as many seem not to be the case. At any rate, I have been looking into catback systems for the GLC 63/63s models only, there seems to be few options at all really other than Capristo, which seem to be a bit of a ripoff if I am honest due its price and what it represents, it is not even made from titanium or inconel for that price!?

Within this site, there have already been several threads on this subject yet I was unable to really see any realistic offerings that have not already been mentioned below.

Many of the typical and high end makers seem to offer plug in systems for the ECU management/ remapping etc etc and or perhaps downpipes with little to no cat back options other than paying through the nose for a one off system. Contacted via email a dozen or so well known brands with only 4 of them replying. One brand contacted me and wondered if they could have the use of my car for the R&D of a one-off system, of which afterwards they would charge me full price at around 12k. Yeah that is just not going to happen. Nope!!!! They never even mentioning any contractual obligations for the protection and safety of the car prior/ post R&D as well as not to mention any discount for the use of my car.

This is what I have seen thus far in no order of value and or preference:
A) http://www.fi-exhaust.com/product/mercedes-benz/glc-63 - Superfluous remote system and controller in my eyes, as the car already has this option innately. Aside from this fact, the system does look good from a glance.
B) https://redstarexhaustusa.com/merced...-sport-exhaust - beautiful system from Redstar Exhaust and one that seems to be made very well with good materials, welds etc etc and without all the idiotic remote systems and poser apps.
C) https://redstarexhaustusa.com/merced...gls-ml-exhaust - Also from Redstar Exhaust yet without the valvetronic compatibility.
D) https://capristoexhaust.com/product/...-ces-3-remote/ - Extremely overpriced and offers nothing that another equally well made option could offer although far less without the wallet raping.
E) https://forzaaa.com/products/valved-...enz-glc63-4-0t - Brand is unknown to me as is the price.
F) ?

Looked at Manhart - do not really like any of their stuff; as well as Armytrix with the latter offering nothing I could see for the 63/63s. Although as sweet as that may or may not be, I am pretty sure that it would be around the Capristo price with the same superfluous remote/ app etc etc, which is not needed in my mind other than merely adding more cost. Who knows as I can not seem to find any Armytrix offerings for my model anyway...they obviously do a nice C63 offering! Renntech do not offer much in the way of what I need neither does Supersprint, Gottuned, Weistec, Magnaflow, Fabspeed (they have a nice GWagon option), Vividracing, Carid etc etc.

2018 AMG GLC 63s


So lads and ladies, if there are options that can be ordered internationally, well made with quality stainless and no unwanted paraphernalia attached let me know or post below.

Thanks and much appreciated

Later when I can get the pics from phone to PC, I will upload my car' pic here and elsewhere where related. Its a 2018 white GLC 63s with the forged 21" wheels fully kitted out other than the cooled seat option. In excellent condition other than the stock AMG catback, which now rattles when I push the very much missed "loud button" option in any mode.

AMG catback is well made and sounds pretty good. thats why there is no much room for aftermarket as ppl just see no point to burn 3-5 grands or even some 12 as youve mentioned. fix yours , get some DPs and call it a day.

True true…!

Although to fix mine is rather pricey given either the replacement stock for stock or the actual repair itself.

DP’s would be sweet but I’ve been down the modding rabbit hole with various other previous cars and I’m not too interested in repeating history.

So I thought I could either spend $2,500/2,900. (Depending on who’n’where you get the stock unit) on replacing the current unit, $1800-ish on fixing it or just get something else that changes the sound profile with a bit more growl without going down the DP-end he he he. See what I did there? No? Ah well, I’ll be here all night with those lol.

DP would be cheaper of course yet by the time I get a decent set and fix the current Catback I may as well just get a new Catback. Also I do not want the car to be too loud as living in Japan, the locals already indirectly hate foreigners and think they are mindless, ignorant, loudmouths he he.

So I think I’ll just get a new Catback and call it a day, that way my wife doesn’t kill me, the neighbors don’t kill me and the locals living near my car park neither kill me nor damage my car - has happened before.

The Capristo is expensive, but I spent a month looking at all the same options you have listed there. I said F it and went Capristo.


Honestly I could not be happier. The cold start has an insanely aggressive 1 second, then quiets down making it neighbourhood friendly. With valves closed it sounds as quiet as stock unless you get the RPMs way up then it still opens up and sounds amazing. With valves open it’s truly a monster that turns heads everywhere you go. The videos do not capture how loud the valves open are (which is what I wanted).

So this is the Capristo (with Catless Downpipes). I spent a month trying to decide which cat-back to purchase to complement the DP's. I finally settled on Capristo just because they seemed to do the best job at handling terminating the current OEM valve system, handling the backpressure dynamically, and providing a solid quiet and loud mode. I could not be happier. The cold start gives a 1 second beautiful rumble, but then quickly turns quiet and stays quiet providing a neighbor friendly warm up option. But when I open the valves, it is as loud as the muffler delete I had tried previously, and still maintains the AMG undertone. You can see in the video, although the video does not really do justice to how loud the open valves actually are.

I hear you on the expense, I thought it was ridiculous to, but was worth every penny for me now. The sound is such a huge factor if your looking for attention, and Capristo did an amazing job of it for me!

Capristo does sound great and does also look great and I am by no means putting down the product other than for stainless material, you’re paying titanium prices without either the nice weight benefits or the aesthetic sound/ look of Titanium.

Because I’ve spent much money on previous cars as well as actually buying previous cars etc etc my wife would kill me. In Japan buying cars is forever a depreciative venture by rather large percentile chunks that would make any sane man wobble at the knees.

I really couldn’t justify 8k on a stainless badonkadonk (Catback) while post surgery from the nut kicking my wife would give me; recover from the divorce she would then slap me with ha ha ha.

Seriously though, I’d say Redstar this far are what I am looking at both form factor, fit’n’finish, resonant characters as well as the price.

Fi did send a PM but as yet I’ve not heard anything from them regarding price for their offerings. I’ve told them of my basic budget at around $3,500…so perhaps that is far too cheap for what they offer?? No idea yet as I’ve not been informed.

Supersprint do an exhaust for the GLC43 but not for the V8 models such as the 63/ 63s models that I’ve seen. Could be wrong, yet as I’ve said I cant see anything.

My intention is not to just buy a cheap unit and save on the biscuits! At the same time neither do I want to waste money on a superfluous unit not needed for the car other than a vanity pose!? As many have said the actual stock AMG unit is already good enough (not great). If it becomes too much of a hassle I may just go DP and fix the stock unit then call it a day.

id be keen to know the price of the Fi exhaust he’s got, as that is one of the choices I’m torn between. Yet without knowing the cost, I’d not blindly order one.

for sure I’d be keen to see the vid too mate, thanks a bunch.

if you want to PM me the price your mate paid for the Fi, that would be fine too of course if prices on an open forum is not the thing to do!?

cheers. Bloom. 👍😎😄

The weight comparison would be sweet to know on these options.
Stock OEM AMG catback is heavy I know that but not the exact weight.


Cost new - $2,500/ $2,900. Used - $900. or less approx
