i have my 3rd cat gutted. i was just wondering, if i gut the other 2 cats, will it help with performance ? also, would it cause the cel light to come on ? has anyone else tried this, and did it help the power any or cause any problems ?
I recently had my cats removed on my headswapped '97 because one of them melted and blocked the pipe. You need MIL eliminators or a tune to remove the check engine light you will get from having no catalyst. Yes, they also helped performance in my case.

2013 Ford Taurus SHO (TUXESHO) Tuxedo Black Bone stock for now.
I have gutted cats with only a foot of pipe behind them on each side, straight pipes in other words. Sound good, but it does have that "ticking" sound to it, maybe some glasspacks will remove that ticking??
Performance, I'd say maybe it helps in the top end just a little bit, but I can't tell for sure.
thanks for all the input here guys. we dont have emmision testing here on 1995 or older cars anymore, but i dont think i want that pinging and popping noise and i dont want to hurt the bottom end. anyone know how much high flow front cats cost ? is any brand better than another ?
also, are the high flow cats going to help ? or would i be best just to leave it like it is ?
