I just don't know, Rick. According to what I have been told by the folks that sell and install the high flow cats I don't need them. These guys make their money on exhaust systems so I can't imagine they are making it up.
However, as soon as I get a chance to do further research I will. I am very curious about them.
Can someone else add anything to this? Especially someone with some numbers as this has come up before.
