ok so im about to boost my y8 in a couple weeks, gonna get the head rebuilt because the valve stems seals are leaking so i figured i might as well put some arp head studs in and either a cometic or oem headgasket, and a block guard. thinking of running about 10-12psi stock with ac and ps. think i could do it safely? i dont know what intercooler size i should get, im looking at the mishimoto 27.5x11.75 or 24.5x11.75, i want something the would hide nicely behind the bumper, what size are yall running? and also i wantd to run a vibrant muffler 3 inch, would running a resonator on a boosted setup be a waste of money? thanks yall
