Im thinking of removing my catalyst and making a custom manifold / pipe insted all the way from the engine to where the cat use to end.

Besides giving me a warning light in my dash will this hurt the engine in any way? =)

 

No, many have done this. There are pipes avalable with resonators to cut down the noise a little. In addition, if you get the Cobb Accessport (European version) you can not only turn off that light, but have the ability to tune the ecu. They are available from Mazdamaniac.com & RaceRoots.com

 

ok nice what is this cobb accesport?? a new ECU ? is it a big job to mount it ?

 

ohh i red about it now sounds prettyh easy to use you sure i can turn of the warning light with this? =) ..

 

Yes you can

 

Its just a device that plug into your obd2 port and reflashes the ECU. And yes, if adjusted for accordingly the map that you flash onto the stock ECU can disable the CEL.

 

You should check local laws, and how they're enforced, before removing the cat. In the US it's illegal, and there are regions that do annual emissions inspections.

there is always a high flow cat!

 

But is this not something i just can get a mazda dealer to do?? insted og buying the device.. dont they got something to turn if off with ??

 

Disabling a pollution control device is a Federal offense, $10,000 fine, either for you or for them.

You can risk it, they won't.

Ofc ... well anyway i called em today and they told me that even if they did turn it of it would just pop up again next time i start the car.. ? wtf ? will it allso do that with the Cobb Accessport ??? do i have to turn it off everyday?? :-O cant be?

 

Leave the Cobb plugged in and the CEL will be masked until you unplug the Cobb.

 

Seriously so i have to drive around with something hanging out of my OBD ?

Anyway where can i even buy these cat replace pipes?? seems to be hard to find? :-/ ?

 

Incorrect

No, once you reflash the ecu with the cobb accessport the CEL will be disabled from the ECU... there will be no need to drive around with the AP plugged in...

Once the ECU is flashed the CEL wont come back, period... i know this because i have one, and i have a midpipe and my air pump removed and BOTH CEL's deleted... In my state they do yearly emissions testing... ive passed everytime without a problem... the only time i would have a hard time is if they did a visual check..

Search for a 'Midpipe' there a lot out there... and many companies make them

good luck

 

I smell an EPIC FAILED on this guy.

 

Thank you....... you know, when not speaking english as my main language it sometimes can be hard to get the right meaning out of stuff.. im trying so please stop posting stupid stuff like that...

 

Thanks alot for that info dude !

 

Your engine won't have a problem, but you will create global warming unlike the Icelandic Volcano.

The world will get so hot the ice bergs will melt.
