I'm just probing here ! I am building an extension next door to an owner of a brand new AMG MERC 6.3 litre - he drives off to work every morning and I dribble over the scaffolding at the sound of it ! I really want to keep my Vee oem but my god ! Do any people's out there know of a backbox that sounds like that ? It's so low in tone a burbles along ! I no I'm only a v6 but wow ! My boss thinks I'm mad ! Lol ! Any ideas ( I'm only thinking ) with a thought of saving up ! Mine might sound like it (oem) but I can't hear it from drivers seat :race: any ideas guys ?
