Stage 2.5 is where performance meets personality. You get everything from Stage 1 and Stage 2—your choice of S&B or aFe cold air intake plus the aFe Scorcher GT module—and we step it up with the aFe Vulcan Series 3” stainless steel exhaust. The system reduces backpressure and unlocks a deeper, more aggressive tone that matches your TurboMax’s boosted character, while improving turbo efficiency for stronger mid-range pull. Choose your tip finish to match your truck’s style and enjoy stainless durability that stands up to the elements.
