Unleash Your 2.0T — JAC O2 Housing for 2010-2012 Genesis Coupe (BK1)

Your factory primary cat is strangling your turbo. Every time you hit boost, it's fighting a wall of backpressure that kills spool, robs response, and muffles the sound your engine deserves. JAC's O2 Housing rips that restriction out and lets your 2.0T breathe the way it was meant to — raw, unrestricted, and ready to pull hard.

Stop Leaving Power on the Table

The OEM primary catalytic converter is one of the single biggest choke points in the entire BK1 exhaust system. Swap it out with JAC's O2 Housing and feel the difference the moment you get into boost — sharper spool, stronger mid-range pull, and an exhaust note that actually sounds like a performance car.

Features

• High-Flow Design — Obliterates primary cat restriction for maximum, unrestricted exhaust flow
• Direct Bolt-On Fitment — Drops straight in place of the factory cat, zero modifications required
• O2 Sensor Bung — Retains your oxygen sensor mount for full tuning compatibility
• Beefy Construction — Built tough to handle the relentless heat of a boosted exhaust system

What You'll Feel

• Dramatically reduced backpressure across the entire RPM range
• Noticeably faster turbo spool and snappier boost response
• More horsepower and torque — especially in the mid-range where it counts
• Stack it with a downpipe and test pipe for a full, free-flowing exhaust system

Compatibility

• Fits: 2010-2012 Hyundai Genesis Coupe 2.0T (BK1)
