The Milltek Non-Resonated GPF-Back Exhaust System is engineered for the INEOS Quartermaster, replacing the factory gasoline particulate filter-back configuration with a direct-fit performance alternative. Mandrel-bent T304L stainless steel construction delivers improved exhaust flow and a more aggressive tone character without resonance damping.
This system features premium polished tips with hidden clamps and requires cutting of the original equipment system. The 2.75" (70mm) bore facilitates optimal scavenging for potential horsepower and torque gains. Hand-finished construction and CNC-formed components ensure OEM+ fitment quality across the range of Quartermaster variants.
