It actually looked like it was well made though. The shop suspected that they may have sent me a sedan cat, and maybe for the wrong engine.

Here's the rub. I took the car to a trusted (non-muffler) shop to have the work done. I was told this cat was a bolt-on unit... direct replacement. So they pulled the old cat out (had to do some cutting) and didn't realize I had the wrong part until they put them side-by-side.

They were not equipped to weld in a universal cat for me. The car was not driveable. So I spent $200 on labor at the first shop, and spent $120 having the car toed to the closest muffler shop.

They told me I was better off doing what you all recommended... having a universal magnaflow unit welded in... and that I should go and get my money back from the people I bought the Catco unit from.

So I'm trying to do that now. This ended up being a very expensive mistake for me.

The magnaflow unit seems to have worked out great. It didn't solve my rough idle or hesitation issues though (dammit). I'm taking it in for emissions testing today.
