an assumption but just curious if e63 has any chance ~


Also if primary cats are deleted how much quicker than having it on .
thank you for your thoughts and time !!
You will feel the difference in performance when primary cats are deleted.
If only the secondary cats are deleted, while leaving the primary, the gain most likely will be around 5 wheel horsepower.
Resonator delete don't effect power that much.
