I have a 93 Protege dx I need to know what 4-2-1 headers fit this, cold air intake and an exhaust. I can’t find them anywhere it’s either for a newer year. I’ve heard of Kia sephia headers but I don’t know which year to get and I can’t fit a cold air intake to fit also If I had to get a universal muffler what size is the inlet? Like seriously someone help me
