Been giving my Yaris love as it has become my daily driver. Last night I did 30,000 mile oil change, and cleaned the engine. Today I washed it inside and out, de-badged the back (I <3 it). I ordered an Afe air filter 30-10150. Now I'm wondering if I should drill some big holes in the bottom of my airbox and ripout the charcoal filter. I don't want to hurt mpg but I would like more airflow, for sound and any power i will get. I removed the snorkle thing when we bought it, but otherwise it is stock. I'm also going to go buy the 12$ wonder muffler tip from walmart. I actually had one once but the inside rusted out and fell apart or something. So the question is drill 2 big bottom holes in the box and ripout the charcoal filter? or Not?

Also for completeness, tinted windows, mudguards, side moldings, and spoiler. I have these.
