It's taken a while, short version........
Kooks blamed E85 for causing the cats to fail
I contacted Gesi and they stated that their products are designed for E mix
Kooks said that the tune was wrong, causing failure
Tuner jumped in (thx Ted!) and said no way
Kooks sent two Gesi GE-90147 for me to weld in
I sent back the original Gesi GE-90140 cats to Kooks
Kooks volunteered to send cats with the connection pipes. But since I had welded them in, eliminating the rear clamp that was not an option. I had to prepay for the new cats, they agreed to refund the charge this week. The welding is on me.
Kooks states on the replacement invoice they are 850hp cats, but their website says 425. Not real promising, but we'll see how these do.
