Here's my dilemma, as briefly as possible:

My '95 3.8 LX had been running just fine until I was returning from a long trip and ended up refueling on the NY Thruway. I drove 150 miles or so, arrived home and parked the car overnight. The next day, I noticed a loud, metallic rapping or knocking sound on acceleration through about 35-40 mph and 1500-1800 RPM, most noticeable at part throttle...if you wind it up to 2400 RPM there's very little noise, nor is there any knock when climbing steep hills. Cruising at 50 or so, with the windows down, the knock usually disappears completely. I also noticed a white powdery substance on my garage floor, under the front center of the car.

Today I took it to a local garage for an oil change, and their diagnosis is that the left catalytic converter is toast. They say that you have to change the whole converter/Y-pipe assembly, at a total cost of $948! Ouch!

My first reaction is to screw it...I plan to trade this car in within the month. I'll take my lumps on the trade in or sale price. I can't see spending almost $1000 on a car with a Blue Book value of only $2000.

OTOH, I need to make another business trip of 800 miles round trip next week and I'm concerned that if the converter should fail completely it might cause enough back pressure to plug up the whole exhaust system and leave me stranded. (That's what my technician told me might happen). Should I rent or borrow a car instead?

Any advice? Thanks in advance.

I drove around with a toasted left cat for a few weeks, while waiting for my replacement unit from a guy in Ca.

After I swapped them, I determined that all of the honeycomb material had broken apart, and exitted stage left.

$940 for the job?

Dan Newman at Joe Cooper Ford wants $1400 for just the cats w/ TCCOA discount.

Maybe you can get a low mileage Factory OEM unit from the want ads, and pay a local shop a couple of hours labor to swap them.

Well, if you have a 95, then I think your emissions warranty just expired. So that's out.

Second, I can't see any reason that you should have to change the entire y-pipe. A good exhaust shop should be able to cut the cats out and weld new ones in. Total bill - maybe $250-$300?

Or, get a used y-pipe. It should cost, maybe $50? Bear this in mind: My 89 T-Bird has 150,000 miles and 15 years on the original cats, and it passes emissions with flying colors. So I don't see why decent used ones should have problems.

just buy some highflow cat and swap it in. $100 a piece, plus labor, tops out at $300 max.
