Anybody know if the DC JDM 4-1 header for a Type R will fit in an LS? From what I understand the cat will have to be changed, but how about the rest of it?

Speaking of the cat, I'm also open to suggestions on that one, other than Carsound, which I already know about.

Thanks!

 

Yes, it will fit on a B18B, as long as the cat is sized appropriately. The header and B-pipe lengths are the same between the LS and ITR.

I was thinking of using an OEM cat from a CL Type-S when I was thinking about building a new motor. The flanges would probably need to be modified, but the real obstacle would be the cost of the unit.

 

Cool, thanks
