ok i have flowmaster exhaust now but i dont know what kind, like 70 or 80, but it is a dual in dual out. i see flowmaster makes a super 40 that is dual in dual out now, would i get any more power out of a super 40 and would it have a more mean sound to it?

 

it might make it a little louder but not a whole lot,it wouldnt make a big difference to what you have now, and same thing with the power its not going to make a difference here either, if you want to make it louder and for more performance get some good headers
