The cats melted in about 5,000 miles, which included two track days and 50 or so autocross runs. Trips from the NYC area to NJMP, VIR, and Indiana.

The Whipple tune is garbage. They turned off the cat overtemp warning, so there wasn’t even a warning. I didn’t call Whipple because the fine print of their “warranty” is that it has to be installed by an ASE certified mechanic, and I did it myself.

Driveability on the canned tune needs help too, as the throttle pedal vs throttle body map seems designed to give you big tip-in for an extreme sensation of power. It feels cool, but it makes performance driving harder.

I just got the car back from Jannetty and haven’t had it on track yet, but throttle feels a lot better. I have both catless and green cat setups now.

Learning from my experience, I’d use the Whipple tune to get it to a tuner, and get cat deletes for track work.
