I have a 98 JDM B18C in a 96 Honda Civic DX Hatchback. I am using a 60mm Apexi Noir cat-back exhaust. I cut the 60mm flange off of the midpipe and welded a 2.5" flange to mate up to the exhaust manifold. The catalytic converter was eliminated in this process, since the 96 civic dx cat is built into the exhaust manifold.
Emissions is coming up, so I am going to have to get a catalytic converter. I have a Magnaflow universal 2.5" in/out cat sitting in my shop. I will have the correct flanges welded on it.
My question is, is there a b-pipe or mid-pipe I can get that will bolt up with the catalytic converter in place? I read something somewhere a long time ago about a certain Integra GSR pipe that would work, but I can't remember obviously.
I will take it to an exhaust shop if I have to. My issue with that is, I can't find any shops that do mandrel pipe bending.

Thanks in advance

 

Might help to post pics of your current header and exhaust pipe A and B set up.

 

Hey bud, it is just a cat-back exhaust for 96 Civic DX Hatch bolted to the OEM JDM ITR 4-2-1 exhaust manifold. I'll take a picture in just a bit.

 

Pics never hurt and help more often than not. You'll also likely get more responses.

 

I understand completely. Didn't see the need in this instance since it is an OEM setup.

 

Not sure how you could have OEM with a B18C swapped into a 96 Civic DX hatch. And you mention welding.

 

Here you can see with the cat-back exhaust system for the 96 Civic DX Hatchback is designed for use with the D16Y7 engine that has the catalytic converter incorporated into the exhaust manifold. Once it is matted up to the JDM ITR B18C 4-2-1 2.5" exhaust manifold, it eliminated the space the catalytic converter would be on an ITR.
