JAC O2 Housing for 2013-14 Hyundai Genesis Coupe 2.0T

Free Your BK2's Turbo — The Way It Was Meant to Run

If you're serious about getting more out of your 2013-2014 Genesis Coupe 2.0T BK2, the JAC O2 housing is one of the most impactful bolt-ons you can add. By replacing the choked factory primary cat with a full 3-inch 304 stainless steel housing, you'll feel the difference in spool response and pull from the moment you hit boost.

Why the Factory Setup Holds You Back

The OEM primary catalytic converter is one of the biggest flow restrictions in the BK2 exhaust system. The JAC O2 housing opens that bottleneck with a straight, unrestricted path — letting your turbo build boost faster and sustain it harder across the entire RPM range.

Built to Last, Built to Perform

• Full 3" Diameter: Unrestricted flow for real performance gains
• 304 Stainless Steel: Rust and corrosion resistant for the long haul
• Direct Bolt-On Fitment: Works with factory or aftermarket downpipes, no cutting or welding needed
• Gaskets Included: Everything you need for a clean, leak-free install
• Precision Welded: Tight seams, no leaks, no compromises

What You'll Notice

• Quicker turbo spool and sharper boost response
• More horsepower and torque across the powerband
• Lower exhaust backpressure for better overall efficiency
• A more aggressive exhaust and turbo tone
• A must-have foundation for any big turbo build

Installation

Bolts directly to your factory or aftermarket downpipe. Gaskets are included — no extra hardware needed for a proper, leak-free fit.
