Built specifically for the performance-driven enthusiast, this race-spec header features a true straight-through design with no catalytic converter, eliminating restrictive flow and unlocking horsepower gains you can feel across the RPM range.

Direct Bolt-On to OEM Cat-Back Location – No cutting or fabrication needed
CNC-Machined Manifold Flange ensures perfect fitment and leak-free seal
High-Strength Braided Stainless Flex Section with inner interlock liner to reduce vibration and prevent cracking
Dual O2 Sensor Bungs for OEM sensor compatibility or wideband tuning
