QUALITY of exhaust note: to X pipe...or to not X pipe ??

I would say cut out the resonators and the secondary cats and throw in an x-pipe and see how you like it then go from there. If it's too much, put the cats back on.

ok, so I have the car back from the exhaust shop.
removed the 3rd and 4th cats
removed the centre muffler
x pipe install
QUALITY
in a word...smooth. very factory like. no crackling.
Quantity
it is louder than stock, just enough to detect a note.
still surprisingly quiet at idle, and under normal throttle applications.
inside, there is a tiny increase in volume....still quieter than i was expecting.
At full throttle, it has the deepest muted growl this side of a maserati.
IMPRESSIVE ....even go so far as to say perfect![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
In summary.
Subtle.
You would have to describe it as the ultimate factory exhaust ...rather than a modified exhaust.
we have seen the before and after pics countless times......but hey, its only bandwidth....![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)

nice nice,
I was wondering if there is any sound quality if using double x pipe ?? the first x pipe replacing the h pipe and the other one replacing the resonator .... would it be necesarry ?

Newb here as you can tell by my first post. In the next year I'm planning on getting an E55 as ever since my friend and I test drove one back in 2006, i have wanted one. Just need to get rid of the Porsche and convince the wife that this will be a great family car. I'm learning as much as possible about this car, and I'm a pretty damn good mechanic. My question is in regards to the pic above. I see the cats coming off the manifolds, then I see the other 2 cats right after the cross over pipe, but is that a resonator/muffler that the two pipes connect too right before the rear axle?
Thanks all.
Thanks all.

I would have taken a video last night.......except it started to rain
I suspect it would be too quiet....!
Sell your Porsche !?
....what model do you have ?
Will take one over the weekend.....weather permitting

the tubing does look smaller in the pic ! ....but it is 3"
2 reasons.
the bend into the xpipe is a machine bend![Tear](https://mbworld.org/forums/images/smilies/tear.gif)
the colour is deceptive

certainly not the best pipework I have ever seen![Shakehead](https://mbworld.org/forums/images/smilies/shakehead.gif)
but it gives me sound

Setup looks good glad you like it! If you have time, please post up a sound clip, there are countless people on this board wondering the same thing you did when you started the thread and would love to hear your car.

Q, it looks to me that the muffler shop used 2.5'' piping. Stock is 2.75''. If that is the case, you just slowed your car down.
We had a local muffler shop do a very similar job, 2.5'' pipes, on one of our clients 63 and he was down 25RWHP from his earlier baseline.
Have them go at least 3'', since the bends are also crushed.

With the quick glance I gave it, I assumed factory was 3"
Teach me to not take the time out - and spell out what I want
....rather than dropping it off and saying call me when it is done.

As far as power is concerned...I could not tell you if it makes more or less.
I don't give it a hard time, to know if there is a gain.
What I will say is - the traction control is cutting in earlier now... !
On the bright side, note was my sole criteria

Out Of Control!!
i'm not sure why people keep claiming long tube headers will drastically alter exhaust sound or just make a 55k motor loud. i can assure you that it's NOT true (at least not in my case). i'm running long tubes into an x-pipe with no cats or resonator into the oem mufflers and my car is as quiet as stock when cruising at any speed and it's only moderately louder in the cabin when getting into the throttle.
I will be posting vids this weekend of my setup. I know its not a E55 but its similar. My setup is Kleemann headers to 3" dual pipes to a x-pipe (which I think is a properly done x pipe) back to dual magnaflow mufflers tack welded together to fit in the place of the OEM muffler. It is LOUD and not in a good way.

I wish my car was quiet again :cry: I think its the AMG mufflers that quiet it down alot.

I have Vadim's mid section installed (no cats and x-pipe added) and it sounds mean. At first I thought the noise was a little much but after driving with it a couple of weeks I'm really begining to like it. Everyone that has been it my car loves the sound over stock. When I get a chance I'll post up a sound clip.

Since I believe that deleting the resonators will make it louder, I don't think turbulance is what I want. Can you recommend an x-pipe that does a good job at merging rather than creating turbulence?
