Js 70RR or nah

[Jax-dc5r]

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 (?))

Umm maybe with the cat, the header is 4-2, this is my Jdm header .


So what do I need to make this work :/
I'm wondering if it's even worth buying Js header which I was going to purchase second hand for 650 or just use my Jdm header?

You are missing the 2-1 pipe that links to the cat.
