I just wonder, I've already have some mods done on my 2001 Lightning such as superchips and K&N FIPK and a flowmaster but I want to enhance the sound of the muffler just a little bit aggressive, can I take a couple of CAT'S Converter without damaging anything. I heard that if you take some CAT'S out it would improve performance due to the air flow and it would increase a little tone of the muffler to make it more aggresive sound.
