Good info guys.. So looking at a 4inch dump twin cat system into a single 4 system?? All custom stainless. Already have flash tuner but thinkn they'll have to reflash/reprogram getn bigger injectors, Bigger intercooler,ss growler induction,valves an bigger injectors an modifed wastgate better fuel pump to. Cant quite afford to get the relo for throttle,battery an air filter. Going to do most the work except modified wastgate an get put on a trailer to get tuned.. Would like to know if that sounds like a okay set up an what sort of power will I be pushing out?? And if im going down the wrong path cheers? Oh an a b m tranny cooler with thermo fan or pwr, like the boys have said is a must. Going for this setup as its in my price range!!
