Description

.870" Exhaust Header for Honda GX200 & Clone Engines – Ideal for Box Stock & Mild Performance Builds


This .870" ID exhaust header is designed specifically for modified Honda GX200 and clone engines, offering the ideal balance of flow and scavenging for box stock and mild performance builds. Whether you're running a kart, mini bike, or small engine project, this high-performance header helps unlock extra horsepower without over-scaling your exhaust setup.


Engineered for kart racing and small engine performance, this header is a proven upgrade for engines with light to moderate modifications like upgraded carburetors, valve springs, or mild cams.


Key Features:

  • .870” Inner Diameter: Optimized for improved exhaust scavenging and flow on box stock and mild-mod engines.
  • Bolt-On Fitment: Compatible with most GX200-style blocks and clone engines, including:
    • Honda GX200
    • Tillotson 196 / 212 / 225
    • Ducar 196 / 212 / 224
    • Wildcat 223 / 240
    • Predator 212 & 224 Non-Hemi
  • Durable Welded Flange: Ensures a tight, leak-resistant seal to the cylinder head.
  • Support Bracket: Provides strength and durability to prevent the header and welds from cracking under stress and vibrations. 
  • Performance-Ready: Built for karting, mini bikes, and other high-revving small engine applications.


Fitment Notes:

  • Not compatible with all caged go-karts—clearance issues may arise depending on chassis layout.
  • May require custom bracing or a support tab for certain applications.


Why Choose a .870 Header?

The .870" size is a sweet spot for torque and throttle response in engines that fall between stock and fully built. Too large of a header can kill low-end performance, while this size delivers the right flow for 212cc–225cc class engines without sacrificing power delivery where you need it most.


Give your kart or mini bike the performance upgrade it deserves with a well-matched exhaust solution built for real-world performance.

FAQ

Q1: What kind of engine build is the .870" header ideal for?
A1: The .870" header is best for box stock to mildly modified engines, such as those with aftermarket carbs, valve springs, or a mild camshaft. It delivers a good balance between torque and flow.


Q2: Will this header fit my Predator 212?
A2: Yes, it fits Predator 212 and Predator 224 Non-Hemi engines. However, it will not fit Predator 224 Hemi or all cage-style karts due to clearance issues. Always check fitment before purchase.


Q3: Can I use this on a mini bike or just karts?
A3: Yes! This header is ideal for racing go-karts, provided your frame allows clearance for the exhaust pipe.


Q4: Does it come with a gasket or mounting hardware?
A4: The Header comes with a support bracket, but the gasket and exhaust studs or bolts are sold separately


Q5: Why not use a larger header for more power?
A5: Bigger isn’t always better—oversized headers can reduce torque, especially at lower RPMs. The .870" size is optimized for responsive power in small engines with light to moderate upgrades.
