Yonristic Performance Mercedes-Benz W167 GLE 450 / GLE 53 AMG Performance Exhaust

Give your Mercedes-Benz GLE 450 or Mercedes-AMG GLE 53 (W167) the exhaust note its turbocharged inline-six deserves with the Yonristic Performance Valved Cat-Back Exhaust System. Designed specifically for the 3.0L M256 turbocharged inline-6 with EQ Boost, this premium exhaust system enhances sound, improves exhaust flow, and delivers a more engaging driving experience while preserving the comfort expected from a luxury Mercedes-Benz SUV.

The factory exhaust prioritizes refinement and noise suppression, leaving much of the M256 engine's character hidden. Yonristic re-engineered the entire rear exhaust section with a true 3-inch mandrel-bent high-flow midpipe that transitions into an AMG-inspired Y-pipe feeding dual 2.75-inch exhaust outlets. This carefully balanced architecture reduces backpressure, improves exhaust scavenging, and produces a deeper, richer, and more aggressive exhaust tone without introducing excessive cabin drone.

At the rear, the system incorporates electronically controlled valved mufflers, allowing drivers to instantly adjust the exhaust character. With the valves closed, the exhaust remains quiet, refined, and comfortable for daily driving and highway cruising. Open the valves, and the system delivers a bold turbocharged soundtrack with increased volume, deeper bass, sharper throttle acoustics, and enhanced overrun character that transforms the personality of both the GLE 450 and AMG GLE 53.

Every Yonristic exhaust system is precision-manufactured from premium AISI 304 stainless steel for outstanding corrosion resistance and long-term durability. For enthusiasts seeking maximum performance, an optional Ti-6Al-4V Grade 5 Titanium version offers substantial weight reduction while producing an even sharper, more exotic motorsport-inspired exhaust note.

Each system is mandrel-bent, hand TIG-welded, and engineered around factory mounting points for OEM-quality fitment. Installation is completely bolt-on, requiring no cutting, welding, or ECU tuning while maintaining compatibility with factory oxygen sensors to help prevent check engine lights.
