Has anyone Dyno tested the gains for just CAT removal?

[Ron]

Does anyone have the dyno proven RWHP/TQ gain with just an OEM CAT removal? Would like to see the theoretical maximum gain available with really free flowing cats.

Would also like to see the A/F ratios if your dyno operator provides.

Thanks much

I am also interested in this same info.

I have a 95 with only two mods. Smooth tubes and no cats on factory exhaust. I haven't dyno'd though and missed the local Viper Dyno Day due to a Michigan Football game. Now that they can't seem to win a game, I wish I would have went to the Dyno Day.
