hey guys i was looking into a megan racing high flow cat, my cars been doin some weird stuff lately and i think a worn out cat is partly to blame, the car is a 95 and to my knowlege the cat hasnt been replaced, ive heard they are only supposed to last about 6 to 8 years so i figure replacing it wont hurt anyway the questoin, anyone have one of these? or know much about them, good gains? worth it? ne info would be great thanks
