catalytic converter

how do you all pass smog with a catless downpipe? I don’t have a check engine light, would I be able to pass if they don’t do a visual inspection?

Hi Folks, My wife's '02 Beetle, (2.0 and automatic) is in dire need of a new catalytic convertor. I'd like to do it myself. To make my life easier I want to get a bolt-in assembly (also I suck at welding). There's a big range in prices out there. I don't want to spend more than I have to...

I have a 2004 manual turbo and after a few months of owning it the cat converter went bad. The dealer replaced it but ever since then my car has smelled like "engine". My daughter says it smells like crayons. It is so bad that I can smell it in my hair and/or on my clothes for a short time...

Hello everyone, I am in the process of diagnosing some problems with my 1998 Beetle 2.0L (AEG), stick transmission, 173k miles on it. Background info It's had the CEL on for a while now (maybe more than 2 years). No noticeable change in performance (maybe just drop in mpg, not too much power...

This is the continuing saga of mu P0422 issue. *LOL* Last year, I had a persistent P0422 issue and discovered that it was due to a bad catalytic converter. I had my local mechanic replace the cat and one of the O2 sensors (over $900). The issue went away and Beauty drove just fine until a...

I own a 2001 new beetle, 1.8L, standard transmission. Love the car and the way it handles and hugs the road. Do NOT like the fact that I've replaced the catalytic converter three times. Now, my gas mileage is down slightly and I'm getting a check engine light at times. Code tester revealed...

Hello. We bought my wife a 2001 NB GLS 2.0 a couple of weeks ago. Got a screemin deal on it but knew it needed some work. It had a rattling sound from the exhaust that was determined to be the cat. So we had it replaced. We put in a universal Magnaflow cat. To this point the check engine...

I have included photo of inside catalytic converter. I swear it is a round honeycomb ball of material that everytime I would full throttle it would stick in exhaust end of converter causing lack of power and sounded like a wwssshhh sound like a vac or boost leak. One has already come out on its...

Is it possible that a bad MAF would cause the car to run lean, and over time this could've ruined the cat. converter???

Had my 2000 NB for about a year and a half now; just recently the CEL came on (I forget what the codes were, scanned them & they were for the cat). I've also got the typical rattling sound, smell, and loss of HP that comes with a dead catalytic converter. I have already had it replaced once...
