Default emissions crap: i need a cat - how should I do this?

emissions crap: i need a cat - how should I do this?

Too bad that are strict emissions testing here in Ontario Canada. Now I need to sell my Helix downpipe and find another option. I have my up-pipe out too.

There are a few options that I have in mind:

1) get a scoobysport or bosal DP that leaves the stock midpipe in with its 3rd cat. But that leaves me with the stock 2" diameter and the restrictive stock cat. I assume there aren't much gains to be made here??

2) Some sort of HIGHFLOW cat. The only ones I know of are RandomTech and TurboXS. I think this maybe the way to go, but I don't know if this ONE cat will replace the function of all 3 that I will rip out??

3) just the cat back + up-pipe....this will suck. Probably not really an option, but a possibility.

thanks guys!

Using just TXS midpipe cat will not get you through insp. My car throws a CEL only having the midpipe cat(TXS). Maybe you should do what I'm gonna do. Leave the catless uppipe on car but reinstall the stock tbe exhaust. I only have OBD-II scanning done. You can also check out The "active" Perrin CEL fix they have out. Sniffer test won't help there though. Catless uppipe should not effect sniffer test unless they check it when car is cold. Get yourself some 100 octane gas(sunoco) and begin trying cheapest ways to pass first. They can't do anything to you if your car fails a few times. I had a 72Nova years ago and I went through 12 times before I finally passed emissions.

edit-if all you have is a sniffer test, get a local ehaust place to fab up a quick cat to get you through.

get a perrin catted dp...they are $$ but by far the best ones on the market, they have a high flow cat and they guarantee no CEL...theyll also fit with any catback system for the wrx...so if u dont mind spending some extra money to get the best part out there, go for the perrin

we just released the PDE downpipe with race cat but I don't know if it will pass your emissions test. It will pass the US Federal sniffer but CA sniffer is very close - sometimes passes, sometimes doesn't - just depends on the car and conditions. It definitely won't pass a visual inspection.

As I mentioned, I don't know what the emissions tests are like in Canada but thought this might be an option for you.
