like you always say1) a good racing header will not do anything for your bottom end. in fact it would hurt it.
2) a street header is designed for mid range duty, but still affects low end.
3) megan is still crap in my book and always will be
4) who are import tuner's target audience? minimum wage earning teenagers. think about it.
price, reliability, and performance, you can only have two of them
honesly i have a megan header, ive had one on my car for a long time, still in awesome condition, but im sure as far as power goes, it didnt do anything, its pretty much to say you have a header
