Aren't JDM DC5 headers 4-2-1? But I think hes saying that for 60RS to work, youll need a JDM DC5 header+cat. So since you have that, the 60RS should bolt on to the cat no problem. Whereas the 70RR, it comes with the 2-1 pipe so for that to work youll need to bolt it onto a JDM 4-2 header (either J's Racing 4-2 or OEM (?))
