x-pipe and exit in front of rear tires?

id like to know where you get your facts. thats all. im a skeptic and trust NO ONE. i was a skeptic of the X until i built one and i loved the sound alone. the system i built 11 years ago just from some stuff i had read in some mags. i looked at it scaled measurements off the dr.gas X and made my own in 3" as their prices were insane they were the only ones making the X and have been for many years. i spent a t&t night at the track trying to squeeze every .01 i could finally puleld the exhaust off and ran it, i pulled the plugs, jetted it up and it never ran any faster than with my 3" X pipe full system to the bumper. its a street car going high 11s and it worked. there had been a lot of testing, people have formulas to build the X. they do work. just like a merge collector, it looks like a restriction, but they do work. ive built a lot of exhausts, i did try building other style X junctions and they did not work good. were talking exhaust not poop.
