Yes I have the X-Pipe shown above built by Vadim@VRP and NOT the one posted by you or the others.
Again, many people, most being members on this board, love my exhaust note and asked me for the details on my exhaust setup. Not only that but I doubt this is affecting my performance in any negative way and my numbers prove that.
That being said, I am proof that there is NO FLAW in the above X-Pipe by Vadim/VRP as you have posted.

Just because it's on you car doesn't mean that it's not flawed. The Crossover point on that X-Pipe has a VERY small cross section. THe point of the X-Pipe is two fold.
1) To equalize pressure in the exhaust system to allow it to flow more
2) to use the Exhaust pulses to speed up the exhaust flow
An exhaust system is only as large as it's smallest cross section, that X-Pipe pictured makes your system in essence a Single exhaust of small diameter

Sound doesn't mean that it's flowing, in fact some of the best sounding systems in the world are very poor flowing systems.

My argument is based off of facts, both exhaust note & performance on my car. This X-pipe design was tested on my car. So yes, this X-Pipes has been tested for Flaws.
What is your argument based off of? Do you build X-pipes? Do you build exhaust systems? Do you design/fabricate any aftermarket performance parts for any make vehicle let alone MB's? Have you ever tested Vadim's X-pipes compared to the others you talk about? Do you know what Vadim's final specs are going to be for his production X-pipes?

If not your ENTIRE argument is flawed.

And you................have you done a before and after dyno proving anything you have said on this thread let alone any of the garbage you post on other threads

Exhaust Ex spurt
Hey URnext , You notice a trend with E55 pilot posts too. Don't worry he is headed over to the Custom exhaust power gains ,Thread. To Pick my post apart too. And
You know everything I posted is Flawed . Look at it this way , He has to be a challenge to work with. I feel sorry for his work place comrades. Cheers ___PTEngineering

Hey look close at the hand in the picture!!!!! Vandim is giving e55pilot the finger!!!!!!!!!!!:ro lf:
:ro lf:Ladies and Gentlemen:
Here is our MidSection X-pipe prototype.
Stock E55 Exhaust.
The design features:
- 3'' Aluminized Mandrel Bends (Ceramic Coating is an option)
- Direct BoltOn to stock exhaust manifolds and stock catback.
- Will fit VRP, Evosport, Renntech or any other shorty that fits stock H-pipe
- Front pipe is 2.25'' vs. 2'' stock. As big as it can be in order to work with shorty style flanges
- Front bends will be modular, allowing full 3'' capability to mate to Kleemann Headers or any other custom design
- Will allow us to make a RACE version of our shorty header with 3'' collector body
- Has all four O2 sensor bungs. We can turn-off CELs with software
- X-pipe adds nice exotic sound
- Will fit CLS55, E55s, CLS63 and E63s.

I will have more pictures and pricing tomorrow.
Stay Tuned!

I have noticed his post trends for some time now. I usually dont get involved but enough is enough from this guy. This guy is on a mission.
BTW, thanks for the thermostat it really helps keeping the heat down

To URnext and PTE:
I agree with E55Pilot here as have OTHER KNOWLEDGABLE MEMBERS.
Lets not forget that Vadim HIMSELF also said:
If you know anything about X pipes, you would immediatly see the problem with the prototype pictured above and the fact that the merge is WAY too abrubt and would indeed be the choke point in the exhaust. Just becasue it's on your car and sounds good does not mean it's any good or producing any substantial gains. Post up those before and after dyno runs...
Just becasue you don't like what E55Pilot has to say, does not make him wrong.....as myself, Mikey and VADIM have also confirmed. If you think you are right, then please produce some substantive points as to exactly WHY the pictured X pipe above would flow better than a more open X pipe.
Everyone gets bent outta shape around here for EXACTLY THIS REASON. Someone doesn't agree with what someone else posts yet has absolutly no basis for disagreeing other than some lame *** remarks like, "well I have it on my car and it sounds good". Gimme a break.

Really? I must have missed that, thanks
. This was my point exactly, thats why I asked him if he knew what Vadim's final specs were going to be on his production x-pipes. I thought maybe he knew before Vadim.

Dude - you have NO POINT so STFU. Your ony point is that it sounds good which is totaly subjective and really does nothing to further you're argument that your exhaust flows better than a more open X pipe like the one E55Pilot posted. Still waiting for those before and after dynos....

As far as me backing up my statements...well, I haven't claimed anything. You are the one making absurd assertations. Perhaps you'd like to take a look at the Evosport X pipe...
Maybe you should give them a call and let them know they don't know how to properly design an X pipe....Still waiting for those before and after dynos...

Whatever exhaust/mods that are on URnext55's car, it is working pretty good. His car is really fast. I've witnessed his runs twice in the past month both on the race track, and all I can is 
. His numbers are shocking and his exhaust sounds excellent. In addition, his car seems to keep getting stronger and stronger

It would be good to see those dyno numbers on your car. I'm curious to the gains myself.
