hi i am looking to purchase a racingbeat exhaust off line. I have decided to get a full exhaust replacement because the cats on my exhaust are in bad shape. Anyway, i am confused as which to get because of the selection on the website. I dont know which would fit my mazda (an 87 s4 non-turbo fc) and i also want to make sure it fits properly. Anyway take a look at this site and let me know what my best option would be. thanks

Header, presilencer & cat back system for an NA.

 

Do you need to pass emissions or not? If not, the header/presilencer/cat-back would be nice.
