For those of you with turbos, or know a lot about turbo'ing our cars, do you have a hi-flow CAT incorporated into your turbo setup?

If not, how restrictive is the stock CAT?

If so, can you recommend a hi-flow CAT that works with our cars, and retains emissions standards?

Thanks,

I do not have a turbo.
But I can give you my best response.
Yea there are a couple companies making the hi-flow cat even some with the upper piece already bolted for the whole exhuast header manifold.
Im not sure if they do have it but it would totally be a benefit if they did.
Some companies don't have the extra O2 sensor, this kinda sux because LX and EX models have different exhuast manifold.
Even if you were to get a turbo I'd go with a bigger better flowing cat and get an O2 simulator, this onyl because with that turbo the exhuast readings are going to be sufficiently different.

If you want a hi flow cat I heard HKSA jus made one, HP has one already and a few others I can't remember.
Good luck with your future plans.

a cat is a turbos worst enemy. it is restrictive and will restrict power. if you haft to have it get a high flow if ur lucky not to haft to pass emissions just put a test pipe in.

If you looking for a high flow cat, try high flow cat a try. they just came out with one for a 2001+ civic ex, but I don't know if you would pass emissions, but if you are going to turbo your car does that really matter?

Is it easier to blow out of a straw or a garden hose?

a high flow cat will help the exhaust gas pass through your car easier and can make the car faster. combine a high flow cat with a 3 in. downpipe and a catback exhaust and your good. i believe random technologies may have a cat for our car.
