BLOX Racing JDM Honda Header Collector Flange 2.25inch (Stainless Steel) 1988-2002 Civic/Integra B-Series
The BLOX Racing JDM Honda Header Collector Flange is a CNC-machined stainless steel 4-to-1 merge collector designed for B16 and B18 JDM engines in Honda Civic and Integra models from 1988 to 2002. This 2.25-inch outlet flange connects header primaries to exhaust piping for smooth flow and horsepower increases. Ideal for custom header builds on track or street cars.
Key Features
- Stainless Steel Construction: 304-grade material resists corrosion heat and wear for long-lasting performance in demanding conditions. 0.5-inch thickness adds rigidity without excess weight
- 2.25-Inch Outlet: Matches standard mandrel-bent exhaust tubing for unrestricted flow and easy fabrication
- JDM B-Series Bolt Pattern: Exact 4-bolt pattern aligns with OEM and aftermarket B16A/B18C manifolds for secure leak-free fit
- CNC Precision Machining: Tight tolerances ensure perfect runner alignment and optimal exhaust scavenging
- Polished Finish: Smooth surface reduces turbulence enhances appearance under the hood
Product Notes
- Designed for custom header fabrication on JDM-spec Honda engines
- Inspect manifold gasket surface before installation for flatness
- Packaged to prevent shipping damage with foam inserts
Installation Notes
- Professional installation recommended.
- TIG weld primaries to flange using 304 filler rod for strength
- Compatible with ARP header studs and MLS gaskets
