I bought an 04 Wrx a couple months back, Iv always been a muscle car guy but have liked these for a while. Ive done a couple mods since getting it.AEM cold air intake, HKS Hi Power turbo back exhaust, Turbo XS RFL BOV. I recently traded my stock 04 tail lights for 06 tail lights and had em tinted. My question that I have is that I love the way the 06 and newer headlights look, are these interchangeable like the tail lights or am I stuck??? Thanks for all of your help and I will be posting pics soon.
