Magnum R/T Production Engine Question

The Magnum R/T was a station wagon that came with the 5.7 liter hemi or the 3.5 l v6.

If you are taking about a Dakota, Durango or RAM R/T the 5.9 liter magnum engine did not come with the R/T heads nor any other engine upgrades. The engine was no different that the 5.9 in non R/T vehicles. The limited edition RAM R/T Indy truck had a cat back exhaust.
