Sorry Paladin! Yeah that's the only thing they could have been unless they were just the casings with no internals.They looked like polished stainless high flow aftermarket cats I have seen in parts catalogs. I'm sure they would have been precats since they were on the down pipes, BUT they were definitely there. I couldn't see aftercats but I'm sure with their low profile they were tucked up neatly under the car. The Challenger was up on a turntable about three feet high so they were clearly visible in behind the wheelhouse. I was hoping to see more details under the front of the car but couldn't see anything in detail, too dark under there dammit![:@]Could see that it had the independent rear suspension and Flowmasters but again not much detail. Hopefully more will show up in the pictures with the flash!
