Mercedes-Benz S600 V12 - Straight pipe rev

Mercedes-Benz S600 V12 1998 W140 M120 engine - Straight pipe only High flow cats. At the DIY garage redoing my exhaust system. I’m removing the Dynomax superturbo mufflers and putting Flowmaster 10 series mufflers. Here is a clip after I cut the old mufflers. Wait at the end for a nice slow Rev up to arround 5.2 krpm (not red line) sounds awesome!
