My Duster doesn't have a location that is easy to get to for a 3" Pipe to get by the cross member by the tranny. It has two raised spots one for the driver's side pipe and one for the pass side pipe, but the pass is way over towards the driver's side so it would require practically an "S" bend to get the pipe to go through it. I think these headers are longer than what I previously had on there because it worked with 2-1/2" pipe, but it wasn't quite the sharp "S" Curve it will have to be now. I can tell my exhaust guy to put it under the cross member, but I don't know how this is going to effect clearance. I don't drive it in the city much at all, but I think if I put it under the cross member, in a straight line from the header outlet, that I may not be able to clear some of the "Slow" bumps (speed bumps) in the city if I ever did need to go there. Any ideas?
