Description:

Unlock more torque and improved throttle response from your Mitsubishi Triton MK with these Wildcat Tri-Y extractors. Specifically engineered for the 2.8L 4M40 diesel engine in the MK Triton 4WD from 1996 to 2001, the Tri-Y design improves exhaust scavenging across a wider RPM range — delivering stronger low-to-mid range pulling power over the restrictive factory manifold. A popular and proven upgrade for the MK Triton, suits both manual and automatic transmissions, and backed by a 1-year manufacturer warranty.

Fitment

Specifications

⚠️ Please Note: These extractors will require modification or custom pipework to complete the installation — they are not a direct fit to the standard exhaust system. Suits 4WD models only — will NOT fit 2WD Triton variants. Extractor/manifold gaskets are not included. Professional fitting by a qualified exhaust technician is strongly recommended. Please contact us to confirm stock availability before ordering.

• Specifically engineered for the MK Triton 4WD with the 2.8L 4M40 diesel engine
