Description:

Bolt on more power and a deeper exhaust note to your Patrol or Maverick with these Wildcat Tri-Y extractors.

Fitment

Specifications

⚠️ Please Note: These extractors do not bolt directly to the standard exhaust — modification or custom pipework may be required to complete the installation. We recommend having these fitted by a qualified exhaust technician.

Why Tri-Y Over a Standard Manifold?

• Suits both petrol (TB42) and diesel (TD42) 4.2L naturally aspirated engines
• Suits both auto and manual transmissions
• 1-year manufacturer warranty backed by tax invoice

Frequently Asked Questions
