High flow cat?
I asked the shop where I had my headers and exhaust done at about the power difference between a high flow cat and a mid pipe, and if it was worth purchasing. He said I won't notice the difference between the two and that most new cars are already equipped with high flow cats, and that my mag had one. Any truth about any of this?
