Cats - hp testimonials
First of I'm not trying to decide between running with or without cats I know this topic has been beat to death. I have high flow cats and I'm perfectly happy with them. Just curious what kind of hp differences you guys have seen between cats and no cats. I've had them on and off my Z06 and on my trans am and in my opinion it doesn't make much of a difference on a bolt on car. I've heard of ppl claiming they added 30whp by removing the cats, I can only see this being possible on a car thats making really big power. Just curious, what have you guys seen? Until I'm making ALOT more hp than I am now I will be keeping mine on.
