I need to get an exhaust system for my 94 dx h/b, sys. like the apex n1 say dx/si but the dx doesn't have a cat where the si does, so if I get this sys is there going to be a gap where the cat would be on the si?
THANKS

 

do you have a d16z6 like in your sig

 

yes but I have on the dx exhaust on while I break in the motor before the turbo goes on, help anyone

 

Since you have the si motor, when you get the turbo it will be for the si motor. Therefore, you will need to relocate the cat to where it is for the si, which is under the car. So, if you get an exhaust now, before the turbo, you need to get a header for the si motor, a cat for the si, and the exhaust for the si. If you get an exhaust that will fit with the dx exhaust manifold, it won't work with the turbo. And if you get an exhaust for the si, it won't work with the dx manifold. So, wait until you get the turbo to get the exhaust, unless you got money to blow on what will be a useless set of headers.

Cliff's Notes: Wait till you get the turbo to get exhaust.

 

I have the Greddy SOHC turbo kit/31 intercooler, the dp w/the kit ends @ the same place as the dx's exhaust sys, the kit will bolt right on to my dx but I don't want to run 1 1/2in piping so I need a cat back sys, i am not going to run a cat, the turbo will take the place of the dx cat, there would be a gap where the si cat would be so the cat back sys cannot work on a dx and an si
WTF

 

I think that if I can swap a B-series motor in my DX hatch and have my Tanabe super medallion (for a DX/Si) bolt right up with no gaps, then you shouldn't have any trouble with the downpipe for the Z6 bolting up.

 

I will try and illustrate
-----------------------------------cat
(si) L__cat_______muff / (dx) L___________muff

 

I'm still not following. perhaps you could get a pic. Maybe that would help, because on 92-95 civics the cat should be in the same place on all models, it is only on 96-00 that the cat is in different places on different models.

 

they are not in the same place as in my "pic" the dx has the cat right after the manifold and the si 's is under the car
