hahHhHaAAhaHAHa :lmfao: .. sorry.. i just had to let it out.. okay back to the question.. you can run open header?? itll be abnoxiously loud, but then you might throw a CEL since yer car is obd2.. closest your car will ever sound to a muscle car is to get the flowmaster axleback (not sure if they made it for your year) or just bring it to a muffler shop and have them throw one on... unless you wanna get creative and throw in a 302 or 350 under the hood?? hehe..
