I need some help on the exhuast/header fitment. I have a 00 civic hatch and just bought my jdm b18c R motor. What year and model should I purchse the header manifold and exhuast? Im planning on purchasing greddy sp exhuast for 96-00 hatch, 96-00 civic coupe cat, and what headers (year and model)? Need 2 o2 sensors also. I want a perfect fit with no cutting or welding cause the exhuast to expensive to cut it. Help me out. If theres no perfect fitment, I guess es oval muffler and mineke will be my pal. Thanks'

you need a header for a b18c motor, Integra 98+, 98+ so the header will have an oxygen sensor bung already installed, and the exhaust should as well since it's made for 96-00 hatches... not sure how the fitment will be... may need an exhaust shop's assistance.

can I run a 99-00 b16 header for extra o2 plug or will that header be too long and make a direct fit to my exhuast? I need a cat to be in the middle for smog inspection.

 

you can just run your JDM 4-1 with the 2.5 inch collecter for the time being. Toda is great, AN-R, smsp, theres alot out there that will fit. Nothing is just gonna bolt up perfect 100%. I say rock the JDM 4-1 for a bit wait tell ya get some more power and go AN-R or SMSP.

OK to clerify any confusion, What headers, cat, and exhuast are you running on your ek hybrid OWNERS only. Im sure that toda, an-r and others are great headers but thats not the answer im looking for. The question is, what will be best fitment for me, I dont want 2.5 in collector cause I dont want to deal with the cutting and welding on the cat.

 

for a b16 header some people say it wont fit because the b18 motor is longer cause of the stroke, but the other day i saw a tread on how someone used a b16 header on a b18 motor and by the pics of it the header was touching the oil pan or really close to touching...... as for my setup i just used my invidia piping, carsound cat with 2.5 collector with welded flanges and a o2 bung hole with a dc jdm 2.5 in collector header. i have two o2 sensors with obd2 throwing no codes.

Try to find a header off of a 99'-00' Si thats what I need. I have a B20 VTEC swap and I'm running open header for now until I go to a muffler shop to get my exhaust welded back together or find a Si header and bolt them back together.

 

You need to run a 92-95 cat back and a B18 header, then you your cat should be the right length. The header needs an 02 bung and the cat needs one as well.

 

ok this is the thing. I have stock exhuast now for my d16. I used to have an exhuast and sold it. What I did back then was, I purchase a 92-95 civic hatch exhuast (racing medellion), 96+ coupe random tech cat for secondary o2 hole, and 92-95 civic hatch header. Here was the problem occur, It was short about 2 inches or so, so I took it to the muffler place and they added an extra piece to it. Second problem was the exhuast, the middle where it had hangers, 92-95 civic and integras had both hangers where as to 96+ hatch had only 1 hanger in the middle of the car. So therefore, My exhuast was basically dangling in the middle, so the muffler shop had to custom a second hanger just to hold it, but it was still low and scratch the piping big time. So I sold it. I now bought me a R motor and Im gonna run into the exhuast problem again and dont wanna deal with this crap. so i figure what are your setup. I know its a bit confusing but if its to hard, I may just tell the muffler shop to make me a 2.25 inch pipe all the way and my be a ES oval muffler. I rather much have an exhuast.

 

b16 header...any coupe cat with an o2 bung and a 92-95 si hatchback cat back, fits perfect!

 

jus use the jdm itr headers, 99-00 si cat, and customize ur exhaust (cheaper and sure fitment)

if u get the ek hatch exhasut it will not bolt up to where the cat is. and if u get the si exhaust the axelback part will not fit.

 

Spoon or Mugen will make one for the app your looking for. But the price isn't so nice sometimes.

 

The solution I used was, JDM ITR 4-1, SMSP Carsound Cat (17"?) w/ Secondary O2 bung, Apex-i WS catback, b-pipe trimmed about the length of the Cat, for 96-00 Civic DX Hatchback.

If you could get an axleback for a hatch and a b-pipe from the same exhaust manufacturer for a 96-00 EX or SI, you MAY not have to cut (not 100% sure, I don't know the stock cat length).

How are you some of you guys using stock Cats w/ JDM ITR 4-1? I didn't think any stock Cat had a 2.5" inlet to fit the JDM ITR 4-1.

 

Good thread

 

if you want to run with a cat you have to cut the exhaust. other than that the header and exhaust will meet up at the flange w/no cat.
