Faster Turbo Spool & Enhanced Sound
Experience quicker turbo response and a deeper, more aggressive exhaust note with pronounced turbo acoustics.

Mandrel-Bent Stainless Steel Construction
Manufactured from high-grade stainless steel with precision mandrel bends for unrestricted flow and long-term durability.

Integrated Flex Sections
Strategically placed flex joints reduce drivetrain stress, minimize vibration, and prevent cracking under high-heat conditions.

Direct Bolt-On Installation
Engineered for precise fitment using factory mounting points. Includes integrated O₂ sensor bungs for correct sensor placement and system compatibility.
