i just recently dropped a type r into my 00 civic hatchback. i tried using a gsr header and cat with an si b pipe. and its short like 4 inches. which pieces do i need to make it fit correctly? the header i have is from a 95 and the cat is a 00. will that make a difference? i dont know if the cats change in the integra years. if anyone has any input that would be great. im just trying to find a stock setup right now. what did you ek guys use!!!???
