FLP HP Gains w/ cats on

Just curious how much HP I will gain going with FLP's and running the cats. I am also installing rollerockers/springs with the long tubes. Pretty much stock right now with 2OTL and SS intake.

Thanks

I have never had my cats on but I only gained 8rwhp with the cats off! :(
(From stock manifolds with the cat in tact.)

A while ago someone posted some before and after numbers and they picked up 27 rwhp and 27 rwtq with FLP headers and their cats installed. It was a mostly stock car too, but I think that's a little higher than the norm.
