shooting for 300whp on stock b16 with gsr cams and arp's. I am going to build a b16 block and head and shoot for 400-425whp on that. will a 2.5" downpipe and exhaust piping kit work for these power goals or do i need all 3" piping. thanks
A 3" will help quite a bit, as your turbo will spool faster and make more power per PSI, but 2.5" can actually get you quite far. I know 3" fits on an EF, as I've made one myself that fit with a 22mm rear sway.
