Hey all,
Does anybody have any suggestions based on experience where the best place is to buy a new high flow catalytic converter and maybe new oxygen sensors? I see 034 Motorsports has them on a per-order basis with a 2-3 week wait time, but waiting might not be an option.


I got the P0422 (Main Catalyst Efficiency Below Threshold) code today when the CEL came on, and I noticed a big decrease in gas mileage just this morning. Also my car has been chipped, but now the boost won't go over 5 psig, so I'm really thinking it's a clogged cat. Worst case scenario is the turbo has gone bad too. And is this car even worth fixing at 210K miles?

 

I'm also planning on calling LaBree tomorrow to see if they have a HFC in stock.
Any other suggestions?

 

Whoa, what hole did you crawl out of? Labree is your best bet. They should be ale to get one to you within a week I'd expect.

 

I have a Labree on mine. Looks and works great, and was a pretty easy install. I DID have to get a pack of sparkplug foulers and screw them into the pipe, then screw in the O2 sensor behind the cat to get the CEL to go off though.

By the way...their customer service is awesome.
