The factory catalytic converters sit directly downstream of the hot-V turbochargers, creating the biggest exhaust restriction in the system. Replacing them with aftermarket downpipes unlocks +30–50 HP on a stock-tune car and is mandatory hardware for any Stage 2 ECU calibration.\u003c\/p\u003e\n\n\u003cp\u003eThese are the same downpipes used on YPG-tuned E63 builds across the GCC — Kuwait, Saudi Arabia, UAE, Qatar, Bahrain, and Oman — and shipped to customers worldwide.\u003c\/p\u003e\n\n\u003ch3\u003eWhat You Get\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatless Downpipes ($1,999.99)\u003c\/strong\u003e — Maximum flow, deepest exhaust note, full restriction removal.
