BMW M8 (F91/F93) S63 4.4T 2019-2023 High Performance Valved Titanium Exhaust System

This titanium valved exhaust system is engineered to meet high-performance specifications for the M8’s 4.4L twin­turbo V8. It features a full 3-inch diameter flow path from inlet to outlet, a large cross-section X-pipe for enhanced scavenging, and electronically controlled valves which allow you to switch between refined and aggressive exhaust modes. With valves closed, it delivers a composed soundtrack for daily driving; when open, it unleashes a more aggressive, race-inspired tone. Constructed from premium titanium, it reduces mass while enhancing durability and responsiveness. APEX offers this system as a reversible upgrade that integrates with factory valve control or standalone systems.
