JoePoonani, did you actualy read and understood my post, or you just like to write same thing?
i didnt say that headers and full exhaust will add as much hp as turbo, it will be more than 4 thats for sure, again depends on the what piping and exhaust you put in. i know some guys who did the i/h/e and gained an average of 15 hp on their motors.
i would really like to see what combination of intake/header/exhaust increased whp by 15 on a d16y8
as for the op
you want to make your car louder?
umm, why?
