Raul:

There are no sensors within the X pipe. It is basically a crossover pipe that replaces the resonators. Should start at about one inch from the O2 sensors and run all the way past the diff to meet the rear exhausts. I am sure someone else can provide some picturss to help you out some more. Hope this helps.

 

X Pipe:

I am too stupid to link it but go to link so go to

Evosport

Scroll down to the 5 series section and you will see the X pipe featured.. picture and all.

 

A.,

Its not called stupid...its called "early morning i dont want to do anything but sit here and drift away in my m5.com world."

I have it bad today

Silver...there it is without having to link and scroll

If you want a good sound clip of the m5 with B&B's with xpipe check out my imagestation account. I have a couple of videos on there.

IF you purchased the B&B's you probably like a loud exhaust, the xpipe makes them way bettter but you better have permission from significant others (wife/girlfriend/neighbors) before you do it.

let me know if you want anymore info on the setup

 

Guys thank you very much for the info.
I think I will go for the X pipe, I will have it manufactured by my local shop and installed with the Tri flo's so it turns out neater.
Triflow you have a beautiful car and it has a beautiful sound! Congratulations. Tell me, is the sound INSIDE tha car loud while driving?
Thank you very much for your inputs,
Raul

 

That x-pipe sure is "purty." I bought mine last week. However, I don't know if I'm going to install it right away. I'm still waiting for my neighbors to begin complaining about the high revs with the Eisenmann at 6am every morning.

Cheers.

 

Silver,

let me ad lib from a very famous Amercian commercial...This is your brain (egg)....this is your brain on B&B's with Xpipe (smash egg with cooking pan).

I was just talking to garyshooter ( a member also interested in B&B's) and mentioned that the car when geared high but with low speed and pressing hard on the accelerator can scramble the brain something fierce.

Sorry to tell you but it gets loud sometimes...but its sooooo worth it

Bring it on down and lets have a "hear".

One more doubt...

Is the X pipe joined at some point, or is it two separate tubes? This pic looks as if it were joined...
After all, it's called "X" pipe for something...

The x-pipe is indeed two pipes, joined in the middle with a shared opening between the two pipes.

Does anyone know the purpose of this? What if it were two independent pipes?
Thanks

I beleive its purpose it to mix the exhaust gases together to result in a better/deeper sound. It also gives you a bit more crossflow resulting in less backpressure I beleive (not sure on this though).

It has something to do with resonence and sound waves. Individual pipes are not a good idea. The resonance will drive you nuts.

I saw a wind tunnel diagram once about how if you used the correct "H" or "X" at the right length and positioned it correctly, it does something to the waves and creates a suction and sought of acts like a mild extractor.

I'm doing a really poor job of explaining this, so physics guys feel free to jump in.

Just like sound, air and water, travel in waves. You get high and lows, like a squiggly line. If these are intersected at the right time, it can increase flow and change sound dramatically.

If they are joined wrongly it can have the complete opposite effect.

Its like the gas comes out in pulses, and if the pulse crash into each other, its no good, but if alligned properly, its like left right left right left right. It will create a better draw.

Sound engineers can create dead spots in a room, where if you stood there, you wouldn't hear any sound, so they use this same theory to create a sweet spot, and you seat the people in the sweet spot so they get the full array of sound.

Likewise there will be a sweet spot for the sound of your exhaust that gives you benefit, or may just stop you from being disadvantaged. (Sometimes the later is enough).

 

MIB, a ver clear explanation, thankyou very much. It made me realize its not a good idea to hve the local shop manufacture the X pipe for me. I'll throw in the Tri Flo's, drive the car for some time and THEN if it isn't enough, I'll get an x pipe.
Thank you very much for your opinions...

No problem.:cheers:

 

Honestly...who ever thought an aussie floor guy could explain wave pulse theory so well....

Silver....that would be my recommendation to drive the car for a while with the B&B's on...once you get them on there, drive it hard as you really need to hear the real B&B sound...it takes a while to get. My advice...drive on a highway and really push the car. Then you will see the change in sound versus just normal street driving...after driving on the highway you will understand more closely the sound of the exhaust when added with the xpipe
