Do exhaust systems that split into two after the back axle using a Y piece, which do not have any muffler box after the split have equal pressures out of the pipes ends?

Is it important to have equal pressures, does it make the sound better?

 

Well, simple physics tells us they won't have exactly the same pressure because one tip is longer than the other from the split after the axle. With that said though, the difference would be very small especially if you are talking about a system without a muffler. When i say small I mean small enough that you would not be able to percieve a difference listening to one tip vs the other. Btw, if your looking for a great sounding exhaust system go with the SLP loudmouth, its awesome sounding.
