hi flow cat, yay or nay?

[jas98]

got some pace maker extractors for me vs commodore and wondering if a hi flow cat would be any good?

i think i can get it free (as im oretty sure its high flow)

me car has:
2.5 inch cat back
plenum spacer
CAI
corvette servo (auto)
soon to be extractors
in future a dyno tune possible or a tune of alike lol.

would it be worth it? would it increase fuel uusage with the hi flow cat or will it stay the same?

cheers

On a V6 I wouldn't bother. It will use more fuel because you will put your boot into it more.

Nay.

[jas98]

so it will use more fuel? hmm thorght so, as the stadard cats flow quite well on teh commodores i hear?

it mite just be a new cat im not sure, how could i tell for sure? should it have "hi flow" written anywhere on it?

cheers

hmm was thinking of getting a highflow for my vr v6. as far as exhaust modifications apart from extractors (got them already!) what else would you do to it?

[VS-S-PACK-UTE]

i got a highflow on my ute however i done a bit to her and have a full exhuast system, however i did notice a little bit of differnce with the highflow, didnt notice any differnce in fuel usage either, i reakon if you got spare cash go ahead if ya dont spend it else where first, good luck
