I took my car to Big Al’s early in August--a 2006 Acura RSX with only 100k miles. My exhaust had come loose at the flange where it joined the catalytic converter. They welded a piece with a new flange to the pipe, but said I had to have a new converter because they couldn’t use the existing flange. My converter had been working fine, and I should have had them show me to see if there was a way to save it. Anyhow I went along with what they said. Then, when they got that done, they told me my exhaust manifold had a crack and was leaking. I was suspicious of that since it wasn’t leaking before, but had no way to prove it. (Later, I took the old manifold with me and inspected it closely for cracks. I found none, and if it was leaking it must have been caused by something they did while disassembling the system.) Next they told me they couldn’t find a replacement manifold. So I got an aftermarket manifold on E-bay, which they had to drill out a bit because the holes didn’t line up right.
Anyway, after two weeks and almost $1100, I finally got my car back. But less than 1500 miles later I started hearing a tinny noise under the car. I couldn’t see anything, so I took it to my mechanic. He said it was the new converter, the bedding inside had come loose. Not to worry, I thought, the converter has a 1-year warranty. But when I took it back to Big Al’s they said it was damaged by my car not running right, causing too much heat in the converter. They refused to honor the warranty. I checked with my mechanic who has serviced the car for 2 years, and he said there was nothing wrong with my engine, it had always run well and never had any codes. I researched on the internet and found that the discoloration on the converter they claimed was proof of overheating is actually normal for stainless steel and occurs at around 840 degrees, whereas the converter itself normally heats to 1200-1600 degrees. So I’m stuck with a rattling converter that cost me almost $750.
