well a lot of the aftermarket exhausts will be shiny....you can always flat black it w/high temp barbeque paint if you dont like the shinyness, as far as sounding wise, a 4 banger will never really have a really deep tone, the best sounding ones i have heard were the greddy evo catback exhaust, and apex NI catback exhaust, as far as the header goes, it wont make too much of a noise difference. The exhaust will make all the noise and it will bolt on from the catalytic converter back, let me know if theres anything else you wanna know
