So I just got a 2000 Impreza Wagon, and I love it. Mainly I have just done interior and sound upgrades, put some new rims on, and put my ps2 in there with an LCD screen. I am doing a tint next, then an alarm. After that I want to do an intake and exhaust. I need to know what kind of exhaust to get, which would be best? and whether or not I should get the 2.5 hood and paint it then just do a regular intake with that OR ( I am pretty handy) make my own cold air intake where the stock one goes. I would like some direction on this as I am new to working on cars. Which one would get me more horsepower and better performance? Thanks all help is appreciated
