Is there exhaust headers for the 2.4l ?
is the car completly stock right now. the reason i ask is installing an aftermarket header on a stock car wont do much but if you couple it with an intake system and a full exhaust you will benefit from that better. and because the car is so new you might want to check for parts that are for other cars with your motor.. the scion tc has your motor as well as the camry if im not mistaken. so give that a try
