ok i bought a 2.3 for 1300 them i got a good deal for a 3.0 so i got that too.(2500) both are 98. i decided to fix up the 3.0 but i ran in to some problems. i current drive a 94 accord, so i figured just swap the parts. but my greddy catback it about 6 inches too long but thats an easy fix but when i really looked att hee piping the center section (where that resonator is) the stock piping is considerably larger (circa .5") but in the inlets are kind small.the rear section is a little smaller piping (circa 2.25"). just wanted to know what size piping all the 3.0's were running. and also when i look at the too sidebyside the 3.0 is lower then the 2.3, is that normal? ill try to get pic on friday. thanks
