Since this is all getting quite comical I thought I'd try to show how other people fab their X pipes:
Notice how smooth the merge is on all these examples ??

To tell the truth, they do like nice. Does looks matter, probably not. Let me ask you a question, besides looks what make these so much better then Vadims? You mention that the merge is so much smoother but why is that better and why is different bad, as long as results are tested and proven to work it shouldn’t matter…should it? Have all of these been proven to perform better, sound louder, and flow better? If yes then post some results and people could make a better decision on what to go with. As for me, I don't much about the whole MB modding scene and how some designs are better than others. The best I could do is choose a company that has a reputation for producing quality product and trust that. So far Vadim hasn't steered my wrong and not once have I felt disappointed with any of his mods. His product are dyno tested and results are posted for everyone’s viewing. He's always worked with my in every way and is a great guy.
Your opinion is appreciate so please post back.

It's pretty clear that this particualr mod has been developed to keep costs down as much as possible and for those looking for a better sound.

Just so you all know ... I used to use a supersprint Xpipe ... it was just too loud for me so I put the resonator back on. The dyno difference was close to 10rwhp when I removed the xpipe.

You mean you gained 10whp after removing the X pipe ? If so, I don't doubt it. Exhaust system design is a balancing act and many modern day exhausts use many different computer simulations to determine practicality and/or performance only. Just slapping something like an X pipe into and exhaust can sometimes have good and bad effects....there are however some rules that remain true to any design.

Sure it does
Your a joke! I bet you telling me to STFU was the only time you ever told somebody that. I also willing to bet that you were picked on all the time at school. Your pathetic, the only time you have ballz is on the internet.
As I told you already, next time you better say that to my face tough guy.
What a loser.

Also I use the Supersprint longtube headers Supersprint 100 cell cats (was using supersprint xpipe) then stock mufflers. So I would assume it was all designed together not just slapping something on.

Here's mine from VRP
Vadim did a custom on my C55 that looks like this.
Fire away at your critiqe LZH and E55 Pilot ! I don't mind.

Guys, LZH and E55Pilot amongst others are correct... The first pictured PROTOTYPE is a bad x-pipe design. No need to get all worked up about it either.
Sal your car is a monster, but trust, it is not due to that x-pipe lol.
What is wrong with the x-pipe pictured is the way it forces the exhaust to work around sharp bends and the fact that the merged area is entirely too small. This is why we mandrel bend pipes, so exhaust gases have a smooth flowing path to exit the engine. And for the latter point; trying to force two exhaust banks through a merge area roughly the size of a single pipe isn't going to help performance at all.
No, I am not a tuner. No I haven't brought anything into the MBWorld. Gents... An x-pipe is an x-pipe is an x-pipe, they've been around for years and there's no secret to them.

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've currently got Kleemann headers, so no front cats, and Evosport Resonator Delete pipe
Will your x pipe fit into my system? What will it replace?
Thanks mate

Exhaust sample pic Supersprint !
LZH , I know these pictures on your post #76 , seem to have the head Flange issue ,were they bolt to the Cylinder Head. #2,#6 & #8 flanges are 90* Off. Now, I don't Jack about exhaust tuning , but what M-113 heads did these things FIT. Please enlighten me. You May reference the attached sample pictures. Cheers ___PTEngineering

since the x pipes look so close together it looks like a very strong person pinched them together. it looks like a single pipe in the middle. but i know nothing about exhausts. see! unfounded criticism without the nastiness. hope the final design works well.

I have to agreed with "LZH" and "E55pilot". I personally saw it on AMGSC's car and drove his car too. I was very disappointed the way it sound. It seem the the X-pipe (I actually renamed it the U-pipe) designed by Vadim is too restricted because every time I floor AMGSC's car, you get the nasty backfire sound.

The merge area is comparable to single 5'' pipe in size. 5'' pipe flows more than two 3'' pipes.
Two converging 3'' pipes into this area have no restriction. The reason the other X-pipes are made that way has to do with cost. It is cheaper to make.

The front section of the MidX-pipe will be modular and will allow fitment to stock or any other shorty, inclduign Kleemann. I will post more details as we progress this week.

IMO I think my xpipe on my c55 looks like garbage. But hay I spent $300 for a cat back pipe job. I even joke with people that the exhaust guy turned the heat up and low wire speed to burnt a big scavenging hole and called it a day.
I guess you get what you pay for...
