Alright, I've got a 4" jap can on my corsa sport (1400) and i've took the middle box out to make it louder, it didnt slow it down, but im wondering if i put a de-cat on it will it slow it down cause it's loosing back pressure, stay the same, or even make it abit faster?

back pressure will be fine if the bore of the system before the back box is the correct size for the engine.
