yes you can definately run 15 psi safely on that set up. high flow cat if you are lazy and dont wanna swap out the straight pipe when doing emissions..both are good..straight pipe produces more hp though. but if you run with no cat and 3" downpipe and catback your car is going to be loud. but you missed 1 important thing. BLOW OFF VALVE. the purpose of a blow off valve isn't to make noise (only ricers think that). with a 2G and you try boosting 15 psi.. the blow off valve won't hold it. Get a greddy type-S or hks supersequential or blitz or some aftermarket blow off vavle..or even a 1G is good if it's crushed. and if you're gonna get a blow off valve you might as well get hard intercooler pipe..at least upper intercoler pipe. sinceyou're gonna need to buy a flange for your aftermarket blow off valve.. you could just buy an intercoler pipe that is flanged for the blow off valve that you want..saves a few bucks in the long run and provides more horsepower. but yes you can run 15 psi safely..that's what i run..15-16 psi on stock T-25 turbo. You wont hit fuel cut until like 18 psi on stock T25.. and a T25 can't hurt your car.. it just can blow up or whatever from wear and tear but a 4g63 can definately hold the power that the T25 is producing. hope all this helps.. later
