i know there has been countless threads about exhausts and what not but i was looking into either the ninosport reverse y pipe with the boomtubes or the pypes x pipe set up. i know there is alot of debate regarding back pressure, which one would out perform the other?

X would produce more hp, and u won't lose any hp/torque with either, it will just get moved up a 100-200rpm's.
