I put a set of Edelbrock TES headers on my 99 R/T. They are only slightly longer than a shorty set, but they came with a y pipe also. I put them on while I had the front clip off. I had to adapt and modify a few things because they weren't exactly made for the R/T. I had to cut and re-weld the y pipe, and also add extra o2 bungs because they didn't come with enough. I also had re-done my cat in 3" so it was a complete custom job. They are nice, and really had no fitment issues. Hope that helps...
