Ok Im relatively new to the WRX. I currently have an 04 WRX and I just ordered a stage 1 clutch and street light flywheel. While I was ordering parts I went ahead and did an aftermarket Up+Downpipe that will go with my existing CBE. I also purchased a V2.0 Cobb Accessport to tune the car with. I was just wondering if there were things I should be looking for or any hidden bumps I might encounter while doing my upgrades? Any advice or help will be greatly appreciated.
