OK, so I fixed the problem with my engine dying, but I managed to kill my cat before I did so (since there was no spark, the exhaust got flooded with fuel, and it would ignite in the cat, which resulted in a blown out cat); so now I am in the market for a new catalytic converter.  Any recomendations?  I am thinking I may as well get ahigh flow one, but I dont want to shell out $300+ for a Radome Technologies one...  I heard some flowmasters are good?  Any comments or recommendations?
