custom exhaust on my 90 300
My trucks is a 90 with about 130,000 but has only 10,000 on the new motor. I have one cat on it know with a single glasspack that splits at the end then into duel at 45 with the longest tips, sound good.But i have an exhaust leak before the first cat which i still have on. I want a header from cliffordperformance.com dual exit. And i was wondering if i had this header would i have to have a cat for my o2 sensor to work right or does the clifford header have an o2 sensor hole.I want to run the header to two seperate little glasspacks to a 45 degree exit maybe flamethrowers but not for sure.:-X23
