My 2007 Outlander needs a new catalytic converter and pipe (#3 on Mitsubishi page), but is not worth putting $650 into dealer replacement. It looks like magnaflow 51539 ($500) is the cheapest stainless aftermarket replacement. Anyone know of anything cheaper, even if it is steel. Thanks.

Both cats for below $500

 

Thanks for the link, it turns out my catalytic converter is fine, it is just the intermediate pipe that I can not find available in steel or aluminized steel. Which is #3 on this page from Mitsubishi.




I can only find it available in stainless steel like here:


It looks like I will have to have it made at a muffler shop if I do not want to pay $500.00 for a stainless version.

 

This what you need?

Question on this diagram: The mid pipe (part 3) -- is that a catalytic converter at the front of that pipe or just a resonator of some sort? I had some custom exhaust work done and they cut that piece out completely and just put in a new section of pipe to replace some that was bad. And apparently this part in question was bad too because it's gone. I can't imagine you could just eliminate a converter without consequences, nor would a reputable shop even attempt it. They told me it was a resonator and that the converters on the V6 are up at the manifold, but seeing some other diagrams and descriptions, I am skeptical. So far I have no check engine light, but I don't want any surprises when I go in for an emissions check.

 

Thanks!!!

Edit: "OUT OF STOCK - Unavailable until further notice" Damn it.

 

There seems to be an O2 sensor coming out of it on mine, so I think cat.

 

Do you have the 4-cylinder or 6? It would be a different setup. And although the part they cut out of my exhaust may have been a third converter, if it had an O2 sensor, cutting it out of the system would activate the check-engine light. I have no CEL. I've been meaning to go back to the shop and ask what they did, but I've had no problems since the repair and also I'm lazy.

 

I have the 6.

 

So I did ask the shop, and yes, that is a 3rd cat converter; however, it is not connected to an O2 sensor, so it does not relay any info to the ECU and thus will not trip any check-engine light. They insisted it would pass an emissions test as well. They never asked me if it was OK with me to cut it out. Shady? A little bit, yes. But I'd still choose that option over replacing with the factory part that cost 4 times as much. The car is 11 years old.
