this could be an absolute noob question...but does installing a highflow cat increase exhaust volume over the standard?

not the volume of gas no, it just allows it flow more freely

[reedyek4]

i meant in terms of noise volume?

^ oh right lol sorry

no it wont, not in any noticeable way anyway

i think it depends on your exhaust setup, if you already have an aftermarket catback exhaust it will probably make it louder. increasing flow generally increases the sound output. if its a stock setup, it shouldn't make much difference. but then again, why would you open up your flow with a hiflow cat just to restrict it again after it so i'm assuming you already have a aftermarket catback.
