E550 4Matic H or X? (Not what you think..)
Before everyone starts warming up their fingers and preparing to type their own opinion about when you should use which setup and when its irrelevant, let me preface my question by stating: I already have a pretty solid idea on what the differences are and what performance gains, or lack thereof, that each provide. Now, onto the entrée.
Lots of threads I see about X pipe or H pipe or Straight pipe. Thing is, 98% of the time, they are in AMG forums. Non AMG here with Stock exhaust. After having my larger resonator removed last week and replacing it with two straight pipes, I noticed it added just a smidge of sound. I like it. However, I wouldnt say Id like a bit more sound but more that Id like a bit deeper rumble. Check some videos on youtube of a regular Charger or Challenger RT with stock exhaust, NO MODS and listen to that idle. Just a low, non obnoxious rumble. I started looking into it and havent found many posting videos or sound clips of H pipes/Xpipes. Not doing a muffler delete and not looking for performance. Nor am I doing any form of cat delete. Just wondering if anyone has any videos of just resonator delete + H pipe, and Resonator delete + X pipe. Wanting to hear differences in these two setups even though they may be minor. Also, for our cars, there are two resonators. From front to back there is a smaller normal muffler looking resonator and then after about a 10in or so, theres another much much larger resonator. Wondering if removing both and having one large H/X pipe will alter the sound much more than just removing the larger resonator and replacing it with an H/X pipe. No need to really debate on which is better, just simply looking for a more apples to apples comparison. Videos seem to work best. Trying to put together a setup that gives me a deep rumble that isnt really all that loud. Opinions are appreciated. Experiences are appreciated even more.

Sig says 12 E550 so 4.7tt . I have a 2014 E550 with Downpipes and i used an X-pipe with E63s muffler and the sound is awesome . H-Pipe does not have good scavenging characteristic vs the X-pipe . Yes we have have turbos and it does not mean much but i feel like H pipes are more for old school applications .

My 57 Chevy is built old school with a 454, and it has the H pipe with 3" exhaust/ headers. I noticed that the sound was definitely better balanced with a slightly deeper tone. In my case the H pipe was installed for tone/balance - I have never dyno'd before and after, wasn't too important.
Curious to see the results here.

deleting either resonator by itself will give you about the same sound, a nice low, quiet rumble. Removing both resonators will provide the same sound, simply louder. I have an X-Pipe and have in several configurations. 2.5" with no mufflers and both resonators, then I removed the larger resonator and replaced with an x-pipe. then I had the other resonator removed. Then i went 3' catless, etc...
I like the x-pipe, but it does tend to add some raspy-harshness, almost tin-y sound, little "TINK-TINK-TINK's" in there at high revs. I too am curious about how the H-pipe would sound, but I've never heard one. Maybe I'll do it sometime just to see, been thinking about changing things up again...
X-pipe vs H-pipe, power wise, the difference is negligible. From what I remember from old engine dyno articles, X-pipe had a few more HP with a little less torque, where the H-pipe setup made a touch more torque and less HP.

I've heard some.video comparisons on different cars, but never on ours. Mainly mustangs and challengers and camaros. The big 3 obviously and the difference is definitely pronounced. However with firing order and different engine characteristics, I assume our engines won't sound anything like that. You wouldn't have happened to take any videos or sound clips of your car as you removed certain exhaust pieces would you?

Deleting both resonators and adding an X-Pipe will barely make a difference (sound wise). I had it done and wasn't happy with it so I removed it (wasn't loud enough). You need to mod your mufflers or replace them with AMG ones to get a nice sound similar to the amg cars. I got a shop to fit the C63 Performance exhaust with the H-Pipe and now I love it.
Muffler mod option that you could do:

Something I had just thought of however, what if someone replaced the smaller resonator with a sound altering muffler? Flowmaster/Borla/Magnaflow things of that nature. Sound would be altered but it'd be so far back in the chain that maybe the sound won't be obnoxious. Obviously that would be far less than ideal for performance gains. But speaking strictly on sound, maybe that would be an incredible difference?

ooph! I have no idea what the laws are, but it is possible it might fail a visual test if you remove them. It will not cause a CEL of increase emissions any though, just be louder.

This is true. Removing both resonators and leaving the mufflers will not be as loud as removing the mufflers and leaving the resonators in place. Honestly, because of the turbos, having the car straight-piped is the best "budget" option. It's loud, but not near as loud as you would expect...as long as you leave the cats in place...

That's true. I do agree that is the best budget option. In my area that can be done for about $100. Thing is, I don't particularly like the tone that comes out of the mufflers at that point. I fancy a lower pitch tone with current volume or lower. Definitely hate rasp also, so it sounds like H pipe is what I would want. However no one seems to have performed said setup. Maybe I'll have to be the first to post about it
If that is what you want, I'd go straight-piped with and H-Pipe and some nice turbo-style mufflers, like a magnaflow. That style muffler will dampen the sound so it's not raspy, but allow some of the volume to come thru. I suggest the Magnaflows because they are reversible and come in a center/offset oval muffler, which will make your install MUCH easier. I suggest using the center position as the intake, and the offset as the outlet, to be able to tuck the mufflers up inside the fender-well and out of sight.

Turbo style mufflers. I'll have to research that. You lost me on those lol And obviously everything else after that was a blur, but I'm trying to understand.

After more reading, your post makes sense. So you are saying go completely straight pipe from front to back but throw in an Hpipe and some turbo Magnaflow oval mufflers? Wouldn't you think that would be a tad loud?
As it stands from what videos I've seen and experiences I've heard from others...
From Quietest to Loudest...
E550 stock->E550 Resonator delete(1x) + Xpipe->E550 resonator delete(1x) + Hpipe->E550 Resonator delete(2x)->E63 Stock->E550 Resonator delete(2x) + Muffler delete->E550 Cat Delete + Resonator Delete(2x) + Muffler delete
Believe I got that right. And from what I've seen. And there's literally only one video on youtube I've seen of a CLS550 with an H pipe but unfortunately also has downpipes so it's really loud. However the tone, not the volume, I kinda like.

I think I saw the CLS550 video, the white one? I like that sound, sounds totally different than mine. If that is what you're after, go for it. Just try the 2.5" pipe/h-pipe(replacing both resonators) with the stock mufflers. If it's not loud enough, get some other mufflers. Aftermarket if you don't want to spend a lot of cash, and E63 mufflers if you feel like dropping $600-800 on used mufflers...

Well guys, I did it. About a week or so ago. And must I say? I love it. H pipe sounds great on startup and no drone as well as toned down once warm. However when pushing it moderately, maybe 2500rpm+, you hear the slight deep gurgle as you move forward. Perfect sound. I wouldn't want it any louder. Definitely better than stock and tons better than res delete alone.

I was actually speaking to a mercedes technician from a performance shop in my area. He highly suggested the x-pipe for a resonator delete because it properly manages back pressure. I’m having my resonator and secondary cats delete this tuesday on my 11’ e550
