high flow cats

whats the right volume for a tuned gtst 5.9 or 7.5litre

i've heard the 7.5 is more commonly used on gtrs but do they also go well on powerful gtsts over 200rwkws or stick to the 5.9?

thanks

Hey Jimbo, I bit the bullet and went for the 7.5lt, as I'm aiming for 250kw. I think you should make your decision on what sort of power you want to achieve. You can get em on ebay for $220 which is a good price, I think batmbl is also selling em, but his prices are a bit more (I think).

Cheers,

Kyran.

thanks for the reply man

yeah i'm over 200 at the moment and its calling for a high flow due to restriction, capable of a lot more.

a few more mods and we'll be looking at 250. so the 7.5 is the goer, sweet

cheers
