Mercedes G63 W464 - Secondary Catalyst Delete Pipes (2018 on) QuickSilver

Sound Architect
A lighter weight component that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that V8 rumble.
Plus: • These provide a deeper note at all rpm • More volume under acceleration - to emphasise that powerful V8 beat • Easy to install - 'Plug and Play' with no re-tuning required • Just as easily reversible (on re-sale?).
Minus: • None that we can think of !
