Agreed. Run cat-less and add a resonator/secondary muffler/bullets etc. if you don't like the sound, but don't run cats. If you really want to, a GESI/Kooks Green might hold up for you. But then again it might not. And if it doesn't, it can cause some pretty catastrophic damage and likely a few g-notes.

I'm not trying to change your opinion on this but have to say it seems contradictory to speak of the R&D that goes into the Factory Cats but then for the most part suggest folks go Catless and run resonators. Maybe I took something out of context or misunderstood your point and if so I apologize.
This is just me personally, I have a hard time swallowing that the factory cat is so much more highly R&D'd over a company that specializes solely in producing performance products that exceed manufacturer specifications. Keep in mind GESI isn't just a name, it stands for "Global Emissions Systems, Inc". All they do is design, development, and manufacture emissions control products for the past 20+ years..
It wouldn't surprise me to learn that GM outsources the stock Cats to the lowest bidding supplier they can find with some sort of financial protection warranty for them in place if suddenly they all start failing. I highly doubt the stock cats are any competition with a GESI cats.

I don't track my car and with as heavy as traffic is around me I'd be lucky if I can find a long empty on-Ramp that I can open it up on once in a while so I'd say 95% time I am not beating on it. I just want to reduce or eliminate the awful gas smell and if possible reduce the drone some. I am confident a company like Vibrant makes a quality product and even backs it up with a 5yr warranty that it'll just work out fine.
