i got Pacey 4to1s high flows some type of crappy exhaust from when i bought my ute. i hated the sound so i got my hands on a Defillipo big boy twin 3", so i got Paceys + Hi Flow metal Cats and the rest of the system is cat back is twin 3" defillipo, sounds f-n awesome dude, and i felt some gain aswell. i think there is only a very slight kw (2-5Kw) gain if i was to change over for the defilipo headers so at this stage it isnt really worth it
