its funny because everyone that said mod the STI is a child with no sense of what it actually means to have a nice daily driver.
like i said, leave the STI alone. even to push the power levels you want you'll be into it at least as deep as what a bike would cost and it will most definitely leave you wanting more. do not mod the STI until your bank roll can sustain it. currently you're having to choose, which means your money situation isn't right.
