Milltek Resonated GPF-Back Exhaust - INEOS Quartermaster - Cerakote Black Tips - SSXINE123

The Milltek 2.75" Resonated GPF-Back Exhaust System is engineered specifically for the INEOS Quartermaster petrol engine. This cat-back replacement delivers improved exhaust flow, enhanced sound character, and premium aesthetics with Cerakote Black tips-direct factory fitment with OEM hangers and minimal modification required.

Hand-finished T304L stainless steel construction throughout mandrel-bent piping ensures durability and corrosion resistance. The resonated design fine-tunes OE resonance points to produce a sportier, more pronounced exhaust note while maintaining street-legal characteristics. Cerakote Black tip finish resists thermal discoloration and complements modern truck aesthetics.
