Ok I have a m185a3 with the na multi with mid exhaust lol, it goes from 4" into a muffler and out into 3". I want to change it to a stack setup due to the sute I have all over the back of my truck. Any sugestions on hwo to conver it? anyone have one there parting out or throwing away? All I really need is the part from the manifold out of the fender, I can fab up the rest. I thought about just cutting what I have and turning some of the bends to try and make them work. but I dont want to cut and find out it wont work and then I am stuck with a truck with no exhaust, and then I would have to pay out the big $ tos get it going again.
