Hye guys long time reader, new poster, I have an H22 and currently am running a 2.5" dp with 3" catback and no cat, the car dynoed at 404 hp and 384 tq, that was a mix of mostly pump gas and a little bit of c16, at about 18psi, the turbo is a t3/t4 60 trim with the .63 exhaust. I am running AEM EMS and precision turbo 880 cc injectors, just wnated to give an idea of the setup, ok now what I would like is to make close to 500 hp and I was just wondering if it is possible with the 2.5" dp, just for the simple reason that unfortunatley, the way the manifold is I cannot fit a 3" dp cause it interfears with the wastegate, basically I wanna know if I can achieve that power level without haveing to upgrade the manifold, thanks for your time any input would be greatly apreciated
