{"title":"G63 AMG","description":"\u003cp\u003eThe W463A Mercedes-AMG G63 pairs the hand-built M177 four-litre V8 biturbo with the most recognisable body shape on the road, and it responds to exhaust work as readily as any other AMG. At Proven Performance Parts, our G63 collection delivers Stage 1 to Stage 3 hardware for the W463A: catless and catted downpipes with and without heat shielding, valved catback exhaust systems, cold air intakes, charge pipes and carbon fibre exterior styling. The M177 mounts both turbochargers inside the vee, so it takes a matched pair of downpipes - and on a vehicle carrying this much weight, the restrictive factory pair is the single biggest limit on the engine. Freeing them drops backpressure, sharpens spool on both banks and releases the power a tune is already asking for.
