Description
Product Overview
High-performance stainless steel exhaust header for 1990-1995 Toyota 4Runner and Pickup with the 2.2L 20R or 2.4L 22R/22RE engine. TIG-welded from mandrel-bent 304 stainless steel, this header improves exhaust scavenging for better throttle response, increased low-end torque, and a deeper exhaust note — especially beneficial for lifted trucks running larger tires.
Key Features
-
304 Stainless Steel: TIG-welded construction resists corrosion and cracking better than mild steel — even in wet climates and off-road conditions.
-
Mandrel-Bent Primaries: Smooth-flowing primary tubes eliminate restrictive factory exhaust manifold bends.
-
Direct Bolt-On: Factory mounting points with OEM flange dimensions — uses existing gaskets. No fabrication required.
-
O2 Sensor Bung: Pre-welded oxygen sensor bung in proper location — retains full ECU functionality.
