Hi all,

I've just been informed by my wonderful dealer that my catalytic converter is toast (after they replaced the ignition coils and spark plugs)... He's quoting me at about $2400 all in, and I'm seeing quite a few options south of the border for about $500-800, but the only problem is, I'm not sure which one(s) are going to get me through aircare - I have a 2004 which will require aircare this fall. Any ideas where to look?

 

Good luck
Don't try the RP Superkat that fail our Ontario Emission test.
I know from personal experience.

You could try the Davesport

 

If you're going for compression tests and stuff to see about engine replacement, you might want to avoid aftermarket as Mazda Canada might void the warranty if your dealership explicitly marks you as having an aftermarket one.

If you're just going to a straight replacement, I'd look to BHR's midpipe and get theirs with the O2 sensor holes and catalytic converter (this way you *shouldn't* get CEL errors).

Make sure to check if it is covered under warranty. The catalytic converter is covered for longer than most components on the car - its the "emissions warranty".

has anyone tryed the Exoticspeed cat?

 

BHR cat won't pass emissions -- it's a 100cpi metal core cat. I believe the OEM one is 1600cpi ceramic (could be wrong). At least, not if they are using a sniffer test on the dyno. Not sure what they do in BC but that's what they do in Ontario. If they just do a scan then you might be ok.

You *might* be able to get away with a non-OEM cat if you can do a 2-stage idle test instad of the dyno test. That's what I got done on my car since it didn't clear the dyno (too low) and all my readings were --literally-- at 0 (but that was with the OEM cat).

 

I passed with a Magnaflow aftermarket high flow cat, under $300.

 

Where?
We need to know the location you tested in please

 

^................don't think I would advertise it...............best left to PM's.

I'm just saying.

 

LOL well ... ok I see how that might be taken the wrong way.
What I meant by "where" was in geographically.

IE) Ontario, Cali, etc.

Don't think there is any danger is revealing that

 

anyone on here using a resonated midpipe / gutted cat for regular driving and putting the oem cat on just when needed? seems that track days kill the cat fairly quickly.

 

That is exactly what I am doing.

Darkbrew and I are setting up a custom midpipe with a Davesport cat to give a try on a E-Test ..... but that project is long overdue.

I had a RP Supercat that failed terribly

 

I may need a new cat. Will probably ask for the old one back from the dealership and gut it. Should make for an interesting sounding exhaust system.

OP - let us know how things work with the dealership & warranty claim.

 

He's from Mississuaga wcs, a bunch of us met up in 2008, which headed to the ballet afterwards.

I'm on an unintentionally made gutted cat. **** timing got my claim denied, however Mazda better swap it out this year or I will be dropping this cat off on their guest services desk at Vogel Dr.
