I believe that those are used to fab up custom headers or exhaust they don't actually go on the car as a U though

Either way why would you do something like that? Do you really think it will give you better performance? I think if I was you I would go with Straight Pipes or at least H pipes. I like Straight pipes with no connection, which is what I have. But that's just in my opinion.

Its BS... how would a u pipe work?? only way I can think of is this... but its like a double "U" basically an H pipe really...

I don't hate, just dislike. :P Na I was curious, I like it and it's better then what I would have came up with.

this thread needs to be deleted to make sure no noobs read this and actually try to put a U pipe or a Z pipe...or the ******* alphabet pipe on their car..

LMAO! They could have the whole undercarriage mazed with exhaust pipes. End up sounding like a lawnmower lol.

Ok so here we go first off we need to get some basics out of the way
its all about finding the right velocity vs volume for your application.
High RPM horse power
Use relatively short, larger diameter primaries and large collectors works best for upper RPM HP
example
Shorty headers are used to make high end horse power
cause they filter in a a bigger pipe faster so the exhaust flows out faster
Good street Performance
Relatively long, smaller diameter primaries with smaller diameter collectors
example
Long tubes are used to help make low end torque by making more back pressure.
now other styles
just keep the theory of volume vs velocity in mind
AR headers (anti-reversionary) headers
uses a smaller primary tube that is put into a larger tube about .5in before ending. doing this doesn't let any exhaust flow backwards great for street use. but not very common
y- or Tri-y. is when it is four exhaust tubes off the flange then two meet up to make a Y and then the other two left make a Y. then come together in the collector. Little easier way of saying it is 4-2-1 combo four come into two then the two into one.
H-pipes increases low and mid-range torque without hurting overall horsepower
usually gives you a deeper quieter sound
X-pipes does pretty much helps even out the flow on your exhaust better by pushing it against the other side
so here is where it starts getting a little more confusing
changing the primary pipe size.
Changing the pipe size in your long tubes or shorties will change things also. that is why most people like using long tubes with bigger sized collectors and primarily tub runners the long tube gives you the low end torque but when increasing the primary size of the pipe it will give back some of the higher end horse power you lost from adding the long tubes.
There is a lot more to go over such as the mufflers, vacuum extraction using your exhaust, cat converters and so on... but i'm to lazy for that much typing
ill finish this later got to go eat
