The reduced restriction directly after the turbochargers helps improve exhaust gas flow while delivering a deeper, louder V8 exhaust note and increased turbocharger character.\u003c\/p\u003e\n\u003cp\u003eManufactured from \u003cstrong\u003ehigh-quality SS304 stainless steel\u003c\/strong\u003e, the downpipes are built to withstand the extreme exhaust temperatures generated directly after the twin turbochargers while providing excellent corrosion resistance, strength and long-term durability. The catless configuration eliminates the restrictive factory catalyst sections to maximise post-turbo exhaust flow for performance-focused N63 builds.\u003c\/p\u003e\n\u003cp\u003eThe vehicle-specific pipe routing is designed around the factory N63 \/ N63TU turbocharger and exhaust connection points. Original oxygen sensors and applicable OEM mounting hardware should be transferred during installation where required.
