Mr Boston

I'm planning on putting a CTR exhaust manifold,CTR cat, and a CTR exhaust on my 2000 ek when I swap in the 2001 B18C1 swap.

My question is, Will everything bolt right up perfectly? And if the CTR exhaust manifold and CTR cat have the bungs for the o2 sensors?

Mr Boston

anyone know?

I dont see why it wouldn't. THe ctr is the same block height as the gsr so you dont have to worry about header clearance like you do with the b16. why are you getting a CTR cat? CTR exhaust should work since its the same chassis as the 6th gen hatches.

Mr Boston

Whats wrong with using the CTR cat? I need it because the ctr manifold is 2.5 inches and I would need the CTR cat to match it up with the exhaust..

ok I did not know that, but it should all hook right up.

Mr Boston

Just found out the ctr cat has no o2 bung.. shucks

if your current setup needs a seconday o2 sensor what you can do is hook up the 2nd O2 but do not put it into the cat just tie it up on the swaybar and leave it, there will be no codes if you do this or you can wire a resistor inline with the 02 sensor but hanging up the 02 will work just fine, when you hang it make sure that you do not get the element of the o2 around anything plastic. when you put the 02 sensor out like that the computer thinks that the cat is working real good cause it reads alot of oxygen from the out side air i ran my car like this for about 2 years before i swap the b16b into my 2000 civic, the b16b ecu does not look for a 2nd 02
this is what i have found so if anyone has seen different let me know

Kteller has o2 bung holes on his website that you can weld into you cat. i was planning on doing this if I went 2.5" cat.

if the cat comes from me, ill even have the o2 bungs welded for you! no charge:

if all done and ordered together

ek9 header/exhaust/cat will fit perfect on ek. i have the header on mine. the header has a hole for sensor on top of collector part. havnt got the cat so dont know about that.

i tried this awhile ago when i was boosted it didn't work for me, it threw a code almost instantly. this was on a 99cx so maybe obd2 enhanced had something to do with it.
