I don't want to be misunderstood-an H pipe or X pipe increases power, just recent dyno testing seems to indicate the X-pipe doesn't do nearly as much as originally thought, plus the expense of an x-pipe kit, which is $80 in Jegs, doesn't make it a worthwhile expense over an H pipe.
Keep in mind that modern OBDII systems (on vehicles with EGR) need some backpressure or you may get EGR flow codes. Try to get that diagnosed for $30.00...
