Kill the Restriction. Wake Up Your 3.8.

Your Genesis Coupe 3.8 is being choked by factory cats. JAC test pipes rip them out and replace them with full 2.5" straight-through pipes — more flow, more sound, more power. Simple.

What's in the Box

• Two 2.5" Test Pipes — straight-through, zero compromise
• Four 2-Bolt Gaskets — leak-free seal, every time
• Full Hardware Kit — bolts right in, no fab needed

Why You Need These

• Kills exhaust backpressure dead
• Unlocks hidden HP and torque across the RPM range
• Deeper, more aggressive exhaust note
• The foundation of any serious exhaust build
• Pairs perfectly with headers and cat-back systems

Bolt-On Simple

Direct replacement for your factory catalytic converters. Everything you need is in the box. No cutting, no welding, no excuses.
