Are you sure you need a new steering arm???? My exhaust came out pretty close to the torsion bar/starter/drag link. I searched the internet for the tightest 180 degree 2 1/2" exhaust pipe and found some super tight mandrel bent pipe. I installed it myself and it came out pretty nice. It only cost $27. I had taken the car to a muffler shop last year and told them to use 2 1/2" pipe off the manifolds but when I installed the 2004R in my Cuda (this year) I found that they had used 2 1/8" with no mandrel bends on the driver's side. Most muffler shop don't have the machines to make super tight radii or to make mandrel bends. There's no point is using larger/better manifolds if your going to choke it down with small non-mandrel bent pipe. So I bought the super tight radius pipe and put it in myself.
