Does anyone know if they make a 5 inch downpipe for the 03-04 trucks and will a 04.5 5" downpipe fit my 03?

No, there is no 5" downpipe for an 03-04 truck. If you want to run a 5" downpipe, then you will need to replace the cast iron elbow & clamp with a newer one from an 05-06 model. Then purchase a 5" downpipe for an 05-06 truck & it will bolt up to the new elbow. The newer model trucks run a true 4" elbow & downpipe where as the 03-04 models run a 3 1/2" elbow.
