The drop is good enough if you dont want to slam your car. As for coils it really depends on your budget, or if country of origin its from or overall best bang for your buck.

Everyone uses Chinese 304SS which is not the same, it is but it isn't. i can guarantee the amount of alloy tolerances between the two vary greatly from the amount of rust i see on all exhausts and the very slight magnetism i get from them; so i know the Chinese pipe has a ton more carbon in it vs USA.
