ok, im just trying to find a high flow cat, then when my mate puts on my dump and high flow cat he said he want's to put the boost up to 9psi. is this safe? it wont cause any damage?
its a S2 GTS-T with POD filter, CAI partiton, BOV, and will have a turbo back exhaust.
Thanks for the advice, i just don't want to damage anything.
