STRATEC Systems covers the exhaust: catless and 300-cell catted race downpipes for the W463 G63 5.5T, a titanium catback with free-flow downpipes and a 4.0T titanium valved catback for the W464 G63, and a stainless valved catback for the W463A G500, G550 and G63 4.0T. Palenon Performance adds a dual cold air intake for the M177 4.0T, and Spool Performance supplies FX-200 and FX-350 high pressure fuel pump kits, a Stage 3 low pressure fuel pump upgrade, a wireless ethanol analyzer kit for the G63 and G550, and vent-to-atmosphere blow-off valve adapters.\u003c\/p\u003e\u003cp\u003eTypical builds start with an intake and catback for sound, then move to fuel system parts when a tune or ethanol blend calls for more fuel. The older W463 G63 uses the 5.5T, while the W463A and W464 use the M177 4.0T, so check your generation before ordering. Catless downpipes are generally intended for off-road use.
