All together its about $900 in parts. $1200 including labour.

The cel came on so I brought it in. They said the O2 sensor was 'seized' and the cat converter wasnt working at maximum efficiency.

What Im wondering is whether RRM's catback will fix all this for nearly half the price.

They are trying to rape you...

And how would a CAT BACK exhaust help you if you are having cat issues? think about it...

 

Time to go to a different shop.

 

The O2 sensor is indeed expensive. No help there. But the catalytic converter can be replaced with an aftermarket unit, or a resonator and O2 simulator install.

 

Take it to autozone and have them scan the CEL and see if the o2 sensor says your cat is bad or just the sensor is bad. You can get a universal bosch rear o2 for ~$100.

 

Let me try to be a bit more helpful... Go run a google search for cat converters and an 02 sensors and and you will see they are trying to rip you a new one. As for the labor, both of these parts can be replaced by you.

1st thing I'd do is check the code yourself. If you have Autozones, Pepboys or the like in Edmonton they will allow you to use their OBD2 to pull down the code. You can then cross check that online to see what it means, or they might be able to tell you.

2nd assuming that the code is correct buy your parts online and do the install yourself to save crazy bucks. It's a simple job with the right tools.

Assuming you can't do the job yourself find a good mechanic that you will only have to pay for labor and source the parts yourself. Good luck.

 

thats what i did for the front o2. spliced it in and it was good to go. OR test pipe and mechanical cel fix for you my friend

 

Thanks for the tips. Yeah Ill go to a different shop and order the parts myself.

If I do have to replace the cat and sensor. Are these pretty much what im looking for?

Thats about $300 in parts. (hopefully they both ship to canada)

 

The cat can be purchased and installed from any muffler shop, I'd read the threads about the highflow cats/vs Non high flow cats here on Evom before making the purchase. (If you have any other restrictions in your exhaust there is little reason to go with a highflow cat, no HP benifit/or show value) Also the RRM magnaflow highflow cat is over priced IMHO. Your basically paying for the fact that it is flanged for your Mitsubishi with the O2 bung in the correct location, but any good shop can figure out where an O2 bung needs to be put.

 

you can even look on ebay for some cats, i think i saw one for 50 bucks and it was a high flow cat from works. and as every one tell you, any muffler shop can make the adaption. just look deep and dont buy the first thing you see

 

universal o2 sensor by Denso worked for me. Only cost me ~$40

 

Ok forgot to give an update. Might aswell post one anyways.

So I figured Id let the environment suffer a couple weeks with a broken cat.
Well a couple weeks later the check engine light just went away.. car still runs the same.

So.. any chance my CEL indicator is broken or did the problem just fix itself?

If it did just fix itself then wow.. that sure saved me some cash. Maybe it was just a fussy gas cap that triggered the CEL and the dealership just made up any problem to take advantage of it...

 

Straight pipe baby! Lol
