i have a 1995 civic four door with a b18c. i was wondering if the yonaka cat back would bolt up? if so which one would fit the best? they come in models for 4 door 96+ but not the 95 four door

also i have a edelbrock header with no cat might buy a hytech rep header too...so would i have to make a test pipe? or would it bolt up to the header?

if i have to extend it how much do i need to extend it?

 

You can use a 92-95 2/4 door exhaust, or a 96-00 EX cat back. They should all be the same piping.

Not sure about the new manifold and test pipe lengths. Can't really tell unless someone has done that exact exhaust swap on the same car with the same motor you have. I am sure that you wouldn't need to do too much work for it though.

 

it should bolt up just fine.

if you get a hytech you will either need a test pipe(waste) or just straight pipe it. or buy a cat and just move it back. they go pretty far back.

 

I have a Yonaka exhaust on my 93 4 door, but made my own turbo down pipe. You don't have to be super exact with the length, just the flange alignment. The catback will move back and forth just a bit.

I though the Hytech was like the other headers where it still bolts to a cat or test pipe.

 

it is there is bolts. but i dont have a cat and have a custom exhaust right now. so it would have to bolt to my edlebrock header or a hytech one. which is a 2 bolt flange.


the yonaka has a 3 bolt flange where the cat would be. but i guess i have to make/buy a test pipe/stright pipe with a 2 bolt flange on one side and 3 bolt on the other. or just extend the yonaka and hook up a new flange
