@autochippen.nl: Exhaust sound upgrade! Changing the downpipes for a set of downpipes without gasoline particulate filters but with 200 cell sport catalytic converters makes for a great sound. No smell, no ‘apk’ rejection and a nice deep AMG sound after this modification. #onlythebest #amg #e63 #e63amg #amglife #amgpower #amgperformance #amggang #amglife #amglifestyle #amg63 #exhaust #upgrade #sound #cartuning #chippen #autochippen #dtmobility #oisterwijk #nederland
