True Dual (X pipe) Vs. Y pipe Exhaust

I guess it has to do with backpressure frome the exhaust in order to achieve better power in the lower RPMs.
I could imagine that a X pipe is less restictive and therefore produces less backpressure, resulting in less power and more noise in the lower RPMs.

With X-pipes, you get almost as much back pressure as Y-pipe however, with a Y-pipe you have two pipes of equal diameters joining into one which is why you get the powerloss due to it being more restricive.
X-pipes create the required back pressure (or almost do) and at the same time have to inlets & two outlets which translates to a less restrictive flow and hence better breathing => more power.. I guess lol

True dual will lessen the back pressure and probably cause horsepower loss.
X pipe = more power in high rpms, along with higher pitched sound
H pipe = more torque(suposedly), along with deeper tone
Y pipe = is pretty much the same thing as the Hpipe
Xpipe would be good for cars that have high horsepower or forced induction because it allows the exhaust gases to escape faster they generally dont sound good on stock or close to stock v6's
Hpipe sounds better, works well will with keeping back pressure in a range that helps the flow of exhuast gases escape.
Ypipe is pretty much the same thing as the Hpipe but is cheaper due to less piping and you wont get the deep Hpipe bubble sound because there is no cross over in the midpipe region.
The whole back pressure issue goes something like this: Back pressure will help "scavenge" or "extract" the exhaust gasses out of the cylinder when the exhaust valves open up.

Great info
thats all we here for man.

You got that info on the 2.5-3.0 y pipe myth. .Going from the 2.5 to 3.0 and sctock CBE will it casue power loss or a bottle neck issue?? I really want a y pipe but can not find one that iis 2.5-2.5( Exhaust depot, has not replied to emails)..
