Thanks! It rolls out real hard. Doesn't even have the quick Z51 gearing down low. I broke 3 rear ends(2 RPM fully built) last year in my low hp Z06. I know about c5/c6 diff from that, and don't want to go there right yet. That is why I didn't push it the first pass.

 

Thanks for sharing your results!! Glad it was as simple as removing the cats. Guess that proves power can drop at the same rpm despite varied exhaust temps. Great info!!
