Some of you may recall my thread a while back asking what a catalytic converter should sound like. After avoiding the problem for almost a year and failing emissions twice, a new cat solved my problems. For those who don't recall, one cat was solid, the other hollow.
Usually I would have splurged and bought the direct fit cat from bma or the local foreign auto parts store but decided $500+ was too much for one cat. I ended up with a flowmaster cat converter from a local muffler shop that came highly recommended. Unfortunately, my dead cat no doubt is the result of an engine problem, be it a leaky injector or whatever. I will have to work on fixing the underlying issue but thought I'd share the results of running 1 good cat and one bad one, with 2 good, functional cat converters.
The difference between test one and two was marginal, and does not warrant posting here.
