EVO help

[black_e92]

Hey guys I currently own a BONE stock 2003 EVO. For some reason it seems SO much weaker than my old 2005 EVO which had a Injen intake , HKS Carbon TI catback exhaust, and Injen intercooler piping. Does intercooler piping, exhaust and intake really make you feel that much difference or what? Can someone help me out please?:thinking:

Even on stock turbo and boost exhaust and intake mods take much more affect than they would on a N/A car, I would say they are contributing. Especially exhaust....

yes, those mods do make a large difference.
