Not sure why people assume the cats on this car are not high flow considering we have seen over 425 whp on DMACC's car with stock DPs back in the day when Shiv started playing with E85.
I ran over 600 whp with my stock cat back exhaust @ 28 psi. I highly doubt a 17 psi map would have an issue with stock down pipes. But making assumptions is what most people do with regard to this platform.
