Description

5450K-1 High-RPM Drag Racing Exhaust Header – GX200, Clone, Predator, Tillotson


The 5450K-1 Performance Exhaust Header is engineered for high-RPM and drag racing applications using small-block industrial engines like the Honda GX200, Clone 196cc, Predator 212, Tillotson 196/212/225, and Wildcat platforms.


This left-exit, straight-back header is optimized for maximum exhaust flow, throttle response, and power delivery in wide-open throttle and high-output builds. It's the go-to option for mini bike drag racers and kart builders looking for a clean, aggressive design with proven dyno results.


Performance Benefits:

  • Dyno-Tested Power Gains – Significantly outflows the stock exhaust system. Delivers more torque and horsepower than intake upgrades alone.
  • Straight-Through Design – Exits on the left side and angles slightly inward toward the centerline of the engine. Ideal for drag-style frames.
  • Improved Throttle Response – Reduces backpressure and scavenges more efficiently at high RPM.
  • Race-Ready Fitment – Direct bolt-on for most 196–225cc small-block industrial engines.


Technical Specs:

  • Header Flange Stud Spacing: 1.75" (center-to-center)
  • Material: Mandrel-bent steel
  • Outlet: 1.25" OD (accepts 1-5/16" RLV mufflers)
  • Exit Angle: Left-side straight-back, slightly angled to center


Engine Compatibility:

  • Predator 212 (Non-Hemi & Hemi)
  • Honda GX200
  • Tillotson 196R / 212 / 225
  • Wildcat 223
  • 196cc Clone Engines


Muffler Options:

Run open for maximum performance, or use the following mufflers if noise is a concern:

  • RLV B91MO (4106) – Less restrictive; performance-oriented
  • RLV B91XL (4104) – Quietest option; ideal for noise-sensitive environments

Important: Due to the extended length and weight of the muffler, always use a reinforcement bracketto prevent damage or cracking of the header tubing or flange.


Fitment Note:

Please review product photos to ensure clearance on your mini bike or kart frame. Some applications may require trimming or repositioning depending on frame geometry.
