Time for Emission Test. Questions about Hi flow Cats.
 

Hi guys.

I'm currently running my car with a test pipe, hytech replica headers, skunk2 exhaust. I'm somewhat done racing on the tracks, so I'm looking to make it passable for emissions. I have a connection that can pass me, but I'm looking to fix it for a long run.

What brand Hi Flow cat works best, and can more or less insure my passing.

Current specs
B20 motor, with about 100k on it.
GSR JDM Tranny,
Stage 1 Clutch
Hytech Replica Headers
Test Pipe(want to replace with some kind of high flow cat)
Skunk2 Exhaust. 2.5 inch roughly exhaust.

Also thinking of changing my headers too, something that doesnt sit too low the ground. But not too pricy. Maybe Type R headers?

hey i was gonna get a magnaflow cat for my type R motor but it ended up not fitting these things are really good and even better if running turbo regardless i heard good things about them and they dont restrict much flow...the inside part is made of ceramic maybe look into it..the cat itself costed around 200$ not sure if priced change much.
