help picking high flow cat for my car?

[Fluxypoo]

I'm looking for a high flow catalytic converter for my 92 Ka24DE s13 to maintain
emissions while improving performance. Heres what ive been looking at so far.
The price ranges arnt very far from eachother at all so it just comes down to the
brand. Let me know what you guys think i should go with
Plans currently for the car is stock motor with I/H/C/E

Get one from PDM Racing. It's a Magnaflow with flanges already welded on and ready to be installed. It's a little more expensive but you get quality and easy installation for your money.

I got a Catco universal high flow cat from frsport.com. It is a universal 3" cat, but the people at FR Sport weld the flanges on for you, so when it comes, all you have to do is bold it on. Comes with everything you need for installation. Cost me $144.00 and I couldnt be happier with it.

Fluxypoo: what kind of header do you have?

the universal catco 3'' cat needs flanges welded onto it.. but its a 2 way cat.. you need a 3 way cat.. or its still going to fail emissions.

if welding isnt a problem just go with a cheap hi-performance magna flow.. u can pick one up for 60 to like 110. only prob i ran into was trying to find a shop nearby that would weld stainless steal for me... gay.
