I have a 99 DX hatch. There is NO catalytic converter on my car. It's just not on the D16y7.

Ok, I haven't done the swap yet, but I did bolt my exhaust system on already. (tanabe race medalion - hatchback model). When I swap my JDM B18c5 into this car, will the header bolt right up to the exhaust with no cat? Or is there going to be a gap where there needs to be one? I know I need a 2.5" flange somewhere too..

I have a testpipe for the civic (testpipes.com), but the part which bolts up to the beginning of the B-pipe has a 3 hole bolt piece. The B-pipe for the d16y7 has a two hole bolt piece..so this testpipe would be useless. I didn't do my research on this so I am trying to figure out how others have done it with a Type R engine into a 6 gen hatch.

Can't compare a GSR swap to this, because the GSR header is a different length. However, I read that the GSR header would bolt right up to a catback exhaust system made for this hatch (with no cat)... if that is true, then the Type R header won't. What do I do???

PLEASE PLEASE help me out with this. If you have experience with this EXACT swap, and if you used a cat-back exhaust system for the hatch, please tell me what to do here..

I am stummmped as a ************.

Thanks-

get a catalytic converter and use ex piping.

 

You gotta be more clear about that.

A catalytic converter for the Type R? Are you saying I should use an EX B-pipe? EX piping won't work..

This is a Type R engine, not an EX engine. The piping will need to be 2.5" for my setup..therefor I need to use my piping that came with my exhaust.

someone here has to be able to help me....

 

Yah, that's what it looks like in the helms manual.

The JDM ITR header is one piece.. so I have to figure out a way to hook this up to my tanabe system.

I am guessing there will be a gap between the beginning of the B-pipe and the header collector. But I can't figure out if it will be big enough to use a Type R cat or not...

****. I know someone on this board has done this swap. Someone out there can shine a light on this situation.

 

flex pipe, y0.

 

It is located in your exhaust manifold.

just have a muffler shop do some custem bends when you get your motor, get a hgh flow cat and relocate it. simple.
