Hi guys, first time poster. Ive recently purchased a white Corolla Sportivo, 05 model, and have been looking into parts for it. Does anybody have experience with Injen intake or AEM in terms of ease of installation? Also what intakes can be recommended in terms of best gains (if any) and best sound. I have searched the pinned post and these answers arent exactly there. Also planning on lowering it (KingSpring lows), and getting a custom 2.5" catback with some sort of muffler with dual tips (any input here also appreciated) Any help would be great! Thanks guys
