Deleted all the cats thanks to my boy who does excellent exhaust fabrication and welding work, 3 inch dr gas style x pipe in place of the 3rd cat... holy crap is it loud now with no mufflers. I may have to end up getting some mufflers but at this point it's not my daily driver so we'll see... I haven't even dared to try to open the cut outs at this point... and oh yea the car definately gained a lot of power, it gets really sideways on the 1-2 shift now but I am on my 19 inch street tires not my drag radials...
