Vibrant T304 SS Exhaust Manifold Flange for Honda H22-Series Motor 3/8in Thick 1993-2001 Prelude
Laser-cut from 3/8-inch thick T304 stainless steel, this Vibrant Performance flange bolts directly to Honda H22 cylinder heads in 1993-2001 Prelude models. Build custom turbo manifolds or headers with port shapes matched to the H22 exhaust ports and sized for seamless welding to standard wall round tubing. Expect corrosion resistance and structural integrity under high heat and boost pressure for reliable performance gains.
Key Features
- T304 Stainless Steel Construction: Offers maximum corrosion resistance and withstands extreme exhaust temperatures without warping or cracking.
- 3/8-Inch Thickness: Provides exceptional strength for high-boost turbo applications while keeping weight low at 1.95 lbs.
- Precision Laser Cut: Ensures exact port matching to H22 head ports with smooth edges for flawless tube welding and leak-free seals.
- Optimized Port Sizing: Designed for standard wall round tubing like 1.625-inch or 1.75-inch diameters used in performance manifolds.
- Versatile Application: Perfect head-side flange for fabricating tubular turbo manifolds or equal-length headers on H22A engines.
Product Notes
- Intended for custom fabrication. requires MIG or TIG welding to round tubing.
- Clean with stainless steel-safe solvents to maintain finish and prevent contamination.
- Ships flat in protective packaging to prevent bending.
Installation Notes
- Professional installation recommended.
- Verify H22 head port alignment before welding. use O-ring grooves if adding seals.
- Compatible with factory H22 manifold bolt pattern. M10 bolts recommended.
