DTM-Tuning M278 4.7L SUV Performance Downpipes is the best way to get that noted V8 exhaust tone with burbles & crackles from your Biturbo AMG engine.
Compatible Vehicles:
Mercedes-Benz GLS550 X166 With M278 4.7L BiTurbo V8 Engine 2016+
Come with:
Double-layer heat shielding - is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes. Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings. It’s very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.
Straight Tunable 02 Spacers - Comes with 3 inserts to restrict flow to the 02 sensor and help set ready and prevent Engine Light conditions when using the Competition model without proper tuning.
Available Options:
GESI GEN2 400CPSI - catalytic converters rated for 1000hp. The new DTM-Tuning GEN2 series provides a significant improvement in exhaust flow over stock and offers the latest emissions technology. EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California).
Ultra high-performance 200CPSI HJS HD - Ultra High-Performance catalytic converters. Made in Germany. The most reputed converters for their outstanding characteristics, quality and durability. These extremely robust converters allow you to achieve flow numbers close to straight pipes while meeting strict Euro 6 emissions standards.
Main Features:
Kit number: MB.GLS550.X166.M278.DP
