i will be swapping a b16 in in a while

i would like to know if the DC Sports Header for 99-00 Civic SI bolt up to an Apexi WS2 Catback designed for a 92-00 civic ex/si.

i am in california and needs to be smog legal that's why dc sports.

thanks for your input and it will be a 96-98 civic ex coupe and the swap will be the SiR-II b16 from hmotors.

thanks!

 

Depends on the cat's length as that's the "joiner" between the two.

 

yea it bolt up if you use your ex catalytic converter in between the header and catback.

 

Well here in California I'm pretty sure we have to use the emissions system of the engine we are swapping in so it could be an SI catalytic converter. Will a header made for 99-00 SI work with a 96-98 b16 from hmotorsonline?

So I'm thinking
Apexi WS2 exhaust catback
DC Sports CARB Legal Header made for 99-00 SI
SI catalytic converter

 

What's an SI catalytic converter? Are you making this stuff up?

 

A D16 Catalytic Converter will not be effective to anything other than a d series. Here in California, we have to replace the catalytic converter with a stock or CARB legal catalytic converter for the engine we are putting in our cars.

So for example...
Stock D16 catalytic converter won't work with a B16
Stock B16 catalytic converter won't work with a D16

The Honda Civic or DEL SOL SI has a B16A2. They use a catalytic converter designed for a B16A2 engine. Hence why I said I might buy a stock Del SOL SI or CIVIC SI catalytic converter.

 

Del Sol vtec has b16 in it

Del Sol SI has a d16 in it

 

oh s*** wtf why wouldnt the si have the better engine?

anyway i know the civic si has B16

 

the ex and si cat are the same
