The DBX707 uses the AMG M177 4.0L twin-turbo V8 — the same engine platform YPG has been building and tuning since 2011, and the same engine that powered the first sub-10-second C63 quarter mile in history.\u003c\/p\u003e\n\n\u003cp\u003eThe factory catalytic converters on the DBX sit directly downstream of the turbochargers, creating significant backpressure right where exhaust gas velocity is highest. Replacing them with aftermarket downpipes is the single highest-impact bolt-on modification available — unlocking faster turbo spool, sharper throttle response, substantial power gains, and a dramatically deeper, more aggressive V8 exhaust note with the burbles and crackles that the factory system suppresses.\u003c\/p\u003e\n\n\u003ch3\u003eCatless vs 200-Cell vs 400-Cell — Which Should You Choose?\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eCatless downpipes ($2,499)\u003c\/strong\u003e — Zero restriction.
