Removed resonator on my 63 (sound clip inside)
Just got it done today. Did this purely for sound so I don't expect any performance increase.
Pretty satisfied with the result...
As I rolled out the shop I'm kinda dissapointed coz it sounds about the same as before but as I travel a bit more then it started to growl. Right now it's making that 'machine gun' noise that the 55s made...

Advice!?!? (Kinda' Long)
I am hoping some of the brainier board members can chime in on this. I have been dying to remove the resonator on my E55 since I got it just for a bit more ballz. I did this to my BMW 850 - which I kow is a totally different animal - and it turned out great. Not too loud, but almost sounds like a Ferrari. I used a Magnaflow X-pipe in place of the center resonator and left the stock manifolds and cats. I went with an X-pipe because the center resonator on the 850 was an open chamber design that equalized exhaust flow from the left and right banks. (I am presuming the center resonator in the E55 is a similar design?) I heard alot of anecdotal input from the BMW board that I would loose torque - gain torque - loose HP - gain HP - you get the point. If anything, I think the 850 felt a bit more responsive down low, and it needs all the help it can get! It SURELY didn't hurt anything. I have read that with a forced induction motor, you don't run near the risk of loosing valuable low-end torque from messing with exhaust back-pressure that you do with an N/A motor. Also, I have read - and it makes sense - that the real restriction in the factory E55 exhaust is from the cats forward and the car really won't respond one way or another to tweaking around behind the cats. SO: here's the deal, I am hoping someone with more real mechanical inclination than I have can say: "You wont hurt a thing by removing your resonator and an X-pipe more faithfully replicates the factory flow than separated straight pipes." Am I on the right track?? Any input greatly appreciated.

Are you planning on doing anything else besides just installing your eisenmann exhaust? I mean are you planning on deleting the resonators or takin out a pair of cats?? If you are just going to install the race muffler, please post a sound clip as I would like to hear the exhaust with just the exhaust itself and everything else intact. TIA

Well right now I've removed the resonators so I assumed when it's time to install the exhaust the resonator won't be there...
As for removing cats, if I'm not satisfied with the volume level I might do that...

If you're in socal, we can meet up so you can hear it. Me posting a video would get me in trouble since I've been asked many times to convert video clips of the baby, and never did it. If I do one of my exaust before the baby.....
Hopefully I get it before the end of the month. HURRY UP NEAL!!!!!!!!!

If that was directed at me, I plan on just doing the exhaust for now, drive around a few weeks and decide if I want more sound.

Maybe we can kill 2 birds with 1 stone. People have been wanting to hear my car too so maybe we can both do our vid at the same time if ya wants...
But please let me know once you get it. I want to hear an eisenmann race by itself with nothing else...thanks again

So as of right now you are stock. Then you will do the eisenmann exhaust and see whether or not you want more sound??? Please hit me up when you get the exhaust done. I am in socal and would love to hear the exhaust as is without anything else taken out or put on. That way I know what it sounds like if I were to get it and not do anything else...

Benzboi and psk145 - please keep me posted on your thoughts regarding the Eisenmann Race system on an E55 with an otherwise stock exhaust. I am gathering that removing the resonator may be an exercise in futility as it already flows extremely well and offers little if any restriction, so I am really interested in how the Eisenmann swap alone will sound on this car. When I did the X-pipe on my 850, I also installed an Eisenmann Race system at the same time. Tough to really know what effect each mod had on the overall sound, though I am pleased with the combination and final result. I will say, Eisenmann is probably the prettiest, highest quality, best sounding system out there. I've got it on my 850 and I had it on my CLK55. Couldn't have been happier.

Great idea! Did it involve cutting, or just unbolting?
My E63 sounds pretty good from the outside already, but way too muted on the inside.
How much difference do you notice inside when you step on it? How about steady state cruising at 60-80 mph - any resonances/droning?
