I have a 97 honda civic with a jdm b18c. I just bought a 98+ jdm itr header.... Will it bolt right up to my catalytic converter?

I currently have a ebay 4-1 header now. What size are most ebay headers?

Deetz

you will need to mod your exhaust as the jdm header has a 2 1/2" outlet

kevinm1981

guess i should just buy a 2.5 test pipe. what would i need to mod to fit the cat?

Deetz

why not get the real thing....

wouldn't gain as much hp with a cat.

kevinm1981

what size collectors do most ebay headers use?

Deetz

umm, you are talking a difference of only 1-2hp, thats it

kevinm1981

I know but that is also just as much as i paid for the header itself.

kevinm1981

I can get a bwr test pipe for 55 shipped or a blox one for 90 shipped.

Deetz

i don't like test pipes because they usually end up making your exhaust sound, and smell like crap, but hey, it's your car

kevinm1981

I used to have a test pipe on my integra with ws2 exhaust and it sounded amazing. Eventually i will get a ws2 on this car.

I'd hate for you to remove harmful gasses from your exhaust at the expense of a few horse power.



Edit: Since you got such a good deal on the header. Sell it for a profit, then get a good hytech header or something and get an exhaust made for your car. OEM replacement catalytic converters are like $70. You'd get a much better exhaust setup with a non-oem header and an aftermarket cat and still be legal and not as harmful to the air. I used to live in Tolleson, I know how bad the air can be in the valley.

hytech headers are for fully built motors, my internals are all stock minus type r cams.

kevinm1981

Anyone else have any imput? Any help is appreciated.

kevinm1981

Maybe i will just go with a jdm itr cat.

Libertariat

What!?

kevinm1981

People have been telling me why waste money on a big bore header when my motor is stock.....

I got the price down on that jdm cat to 109. Might pick that up.

Libertariat

People are retarded. An ITR motor would benefit massively from a large collector from a hytech header or otherwise.

Is that including shipping?

kevinm1981

Nope no shipping. Getting the blackworks 2.5 test pipe for 60 shipped brand new.

kevinm1981

I dont have a ITR motor.

a hytech knock off will do fine on your motor or maybe a RMF knock off

kevinm1981

My car is too low for a hytech or rmf, I would smash it to pieces. I need a header that is barely lower then the oilpan. Later on i will upgrade to something nice that doesn't hang too low and can keep my ps and ac. Like a bisimoto.

kevinm1981

Ok i got the test pipe but still need the donut gasket and header gasket. Where should i get those at?

Deetz

i hate test pipes

- they make the exhaust loud
- smelly exhaust
- lot's of popping on downshifts and deceleration
