i originally installed a borla cat-back system,2 1/2"...then i heard about the restrictions inside the pipes,apparently there to cut down on interior resonnance...so i decided to make my owm,with help from some friends..we installed 2 1/2" pipes from the cats,removed the resonator and put an x pipe in its place,and installed back the borla mufflers...we did not dynoed the car before or after,but the gain in power was really noticeable...the sound is deep and mellow,and i didnt notice any resonnance inside,at any rpm
