I've been looking around for an exhaust system for my CLS63 and came across an Eisenhaus for sale. However its for the CLS55. Are these exhausts bolt on or welded on? Also, does anyone know if would fit a CLS63? I would assume the piping wouldn't be that different.

Won't work!

Ahhhh...thats what I figured. Guess I'll be placing on order for the Eisenhaus race exhaust soon then. I hope it won't be too loud or have excessive drone. Thanks for the help once again

Hey maybe just delete resonator ?? Do an X pipe, the 63 exhaust to me is perfect as is.

That's what I was initially considering. I saw the youtube video comparing the car with and without the resonator and I didn't notice that much of difference. Then again, maybe its my crappy laptop speakers.

Car is LOUD LOUD LOUD with the resonator gone. Got to hear one live. I think this is cheap and can be reversed easily if you do not like it. There are no HP gais however.

Hey Lexal. I removed the resonator a few weeks ago on my CLS55 and replace with straight pipes. You do get a noticeable deeper and louder sound. I only notice it however on acceleration. When idle and lower rpm's, there's only a very slight difference, if not the same as before the deletion.

I am considering a brabus, renntech or eisenhaus Meistershaft(Stole and copied engineering sound from an eisenmann exhaust they use to carry before Eisenmann found out) exhausts. Eisenhaus no longer an idependent distributor of true Eisenmann exhausts. During my research, I found that the Eisenamnn race exhaust is the best sounding exhaust out there. Great at low rpm's and especially when revved. Sounds sooooo good. Anyways, just my .02 cents. You can get soundclips on youtube of most exhaust.

Hmmmm....so the straight pipes didn't do it for you? Was it not loud enough? I'm just worried about spending $600-700 for the x pipe and installation only to realize that I should have used that towards the Eisenhaus race exhaust all along.

I'm with you on that. At least try the resonator delete with straight pipes to see if you like it. Cheap, if you don't like it, they can put it back on. Any muffler place will do it for you. Currently, I don't think they even make an eisenamnn exhaust for cls55. Eisenhaus does. not sure I like it as much as eisenmann exhaust on a regular non amg cls. Might go with either a Brabus, Lorinser, Kleeman or Renntech.

What's the difference between straight pipes and the x pipe?

Not really sure but I think the tech told me with with the X pipe, the air flows better. If air flows better, that would mean it should be a more aggressive sound. I'm not a tech though, so I'm not really sure. I hope someone else will reply to this thread to give us some more advice. My suggestion is to try the straight pipes first before shelling out the $600.00 for x-pipes.

Remember he has a 55 , they sound very different. Our N/A motor produces a better idle tone . here is a couple clips

If you just wan't it louder spend 40.00-140.00 bucks to remove the resonator, drive it a few days , if you do not like it reverse it. That Sprint Booster will make you forget bout exhaust LOL. My buddies CLS 63 with Renntech exhaust sounds awesome but it was too pricey IMO

Good info. I don't necessarily want the car louder per say, but I want more grunt in the lower rpm's. I was actually going to purchase a C63 and I think I'm looking for something similar at startup/low acceleration.

Just a thought. Have a family member or friend drive your car and you follow them in an other with the window down.

Try listening to what your car sounds like from the outside when its moving...

Trust me you will be shocked.
Reason is our cars have alot of insulation and cover all that sound, but the people outside do hear a good note

or you can sit at one location and have them race past you

Agree with this , drive next to your car under load, its sounds incredible.

Here is a thread discussing resonator delete and wider exhaust pipe

Thanks for the help thus far guys. I'm still debating what I should do. I'll keep this thread updated as is progresses.

How do you get the 6.2L motor to sound like this:

Eisenmann exhaust! I wish they built one for the CLS55 AMG. I called Germany and they currently do not. What a shame. Every eisenmann exhaust that I have heard sounds just like that.

AlrightI thought I would give you guys a little update. After much debate, I decided I would go with the x-pipe. The stock exhaust does sound very good and I figured the x-pipe would hit the spot. However, it ALL changed a few days ago when I heard the M5 with an aftermarket exhaust. It was LOUD and was absolute music to the ears. At that point, I decided I want something like that!

So I am now evaluating the very few options that the CLS63 has. I am leaning towards the Eisenhaus Meistschaft Exhaust and after doing some searching it looks like I'll be the guinea pig. The Renntech is just way too expensive and I'm trying to see if I can somehow manage to retrofit the Eisenmann exhaust from another model. Hopefully I'll have it all figured out and ordered tomorrow.

Please let us know how that exhaust sounds. If it sounds anything like the Eisenmann exhaust, I will also order one. Remember Eisenhaus used to carry Eisenmann exhaust. They stole(copied) their technology and had it made cheaper in Korea and then they slapped an Eisenmann's tag on it til they got caught. I don't know if it sounds the same, but would like to hear some sound clips when you do get it install.

That's my main concern, the whole Eisenmann/Eisenhaus issue that was revealed lately. Not to mention, I have a feeling their race exhaust setup will be too loud for me....One last option I have come across is maybe replacing my mufflers with the 09 mufflers. Hopefully the 09's sound more like the C63. I'm going to give my dealer a call and see how much they go for.

Just gave the dealer the call and they didn't recommend it and claimed they couldn't get pricing on it.

By the way, I came across a thread on the E forums and saw there is an Eisenmann for sale that will supposedly fit the the E55/E63. If thats true, then I don't see why not for a CLS55 exhaust to fit a CLS63

Since the X-pipe versus straight pipe versus H-pipe (okay, not as much H-pipe) discussion keeps coming up over and over again as possible subsitutions for the factory resonator, I always like to remind guys that at least on the 55 engined cars that there is ALREADY A CROSSOVER before the secondard cats, so neither an X-pipe or another H-pipe will improve the exhaust flow, pulse or whatever. If you're removing the resonator, straight pipe is all you need to do. I never seen anyone claim that having multiple crossovers on the same exhaust set-up has any sort of value. And as others have said, even if you just use straight pipes, there are no power gains to be had, just a change in the exhaust note.

The resonator is there for the simple purpose to control resonance within the passenger compartment as certain sound frequencies. That's its sole function.

I think the widely accepted consensus is that the factory tuning shops (e.g., AMG, BMW M, etc.) pretty much extract all of the power there is to be had out of the exhaust muffler systems while maintaining normal sound levels. If you want exhaust systems gains, you need headers, and those only after you've improved the engine's ability to consume more air/fuel mixture.

Maybe a 63 owner can comment on whether the 63 factory exhaust also crosses over before the resonator (or not).

I just put an order in for the Renntech mufflers and they are the same for the CLS55 and CLS63... So I imagine the Eisenmann I was looking at earlier from a 55 would have fit my 63.

Stock exhaust on 63. Same as the 55. The crossover is before the secondary cats.
