2009.5 G8 GT, Compare Cats vs No Cats
Mods in my signature.
It was a 5-6rwhp and 1-2rwtq increase with out the cats. With out the cats it is much louder, no drone, and you have a gas smell outside the car. Personally when I get out of the car I like not to smell gas, not that the smell is on me - just do not want that smell. So not having the cats for an extra few horsepower with that smell is not worth it to me.
Just noticed the correction factor was "standard" switched it to SAE and was about the same.
With KOOKs connecting catted pipes, then with KOOKs delete pipes. Sorry for the confusion.
