Choke Your Secondary Cat — JAC Test Pipe for 2010-2014 Genesis Coupe 2.0T

The factory secondary catalytic converter is quietly killing your turbo's potential every single pull. JAC's Test Pipe rips it out and replaces it with a straight-through, high-flow path that lets exhaust gases exit the way they should — fast, free, and unrestricted.

Stop Letting the Factory Hold You Back

Your 2.0T is capable of so much more. The secondary cat is one of the last major choke points left in your exhaust system, and eliminating it means sharper spool, stronger pulls, and a turbo that finally sounds as aggressive as it performs. Pair it with a downpipe and O2 housing for a full, free-flowing exhaust system that transforms the car.

Features

• Straight-Through High-Flow Design — Obliterates secondary cat restriction for maximum exhaust flow
• Direct Bolt-On Fitment — Drops straight in place of the factory secondary cat, zero modifications needed
• Tough Construction — Built to handle the brutal heat of a boosted exhaust system, pull after pull
• Performance Gains — Supports real horsepower and torque increases where you feel them most

What You'll Feel
