sup all...and sorry all...i know this topic came up alot....i did search for information but they seem useless to me

i recently got header + cat conver(16long, 12" oval) + resonator(16"long, 14"oval) + piping (they are in my room, didn't put them on my car yet), all 2.5 in diameter

my question is:<U></U>

my cat will comes right after the header outlet, but how far away from the cat converter should i place the resonator to get most benificial performance in term of sound reduction and power gain?

does it really matter to place it anywhere after cat converter?
