HIAORS 212cc Exhaust Pipe Jet Kit for Predator/GX Clone Engines — Extended TIG-Welded Header & Tuning Jets

HIAORS 212cc Exhaust Pipe Jet Kit is a complete replacement header and tuning set designed to improve breathing, sound and throttle response on Predator-style 212/224/196cc and similar small OHV clone engines.

This kit bundles a TIG-welded extended exhaust header, heat protection, tuning jets and hardware so you can swap the stock pipe on mini bikes, go-karts and utility engines without hunting for separate parts. It’s engineered to match common Predator/GX-style 5.5–7HP clones and includes a small selection of main jets plus an emulsion tube to help tune air/fuel for the new exhaust flow characteristics.

Will this exhaust fit my engine and vehicle?

The HIAORS header is built to fit a broad range of OHV clone engines including Predator 212/224/196cc, GX160/GX200 and many 5.5–7HP non-hemi and hemi designs. It also targets brands and models often used on mini bikes, go-karts, pressure washers and small pumps.

• Compatible with Predator 212/196/224 and GX160/GX200 style engines.
• Listed vehicle fits: Coleman CT200U/BT200X, Baja Warrior MB200, Axis M200 and similar.
• Works with many clone engines from Harbor Freight, Powerhorse and other aftermarket manufacturers.

How does swapping to this exhaust affect engine performance?

Replacing the restrictive stock header with the extended TIG-welded pipe improves exhaust scavenging and can free up breathing across the rev range, often resulting in sharper throttle response and a fuller sound. Actual gains depend on engine condition, carburetor tuning and vehicle load.

• Extended pipe design promotes smoother exhaust flow and reduced backpressure.
• Includes tuning jets to adjust air/fuel after changing exhaust characteristics.
• Can enhance mid-range punch and throttle feel when tuned correctly.

What comes in the box and what tools will I need?

The package arrives with everything required for a basic installation plus simple tuning parts so you can start testing mixtures right away. A gasket, wrench and mounting screws are included to help simplify the swap.

• 1x exhaust pipe, 1x gasket, 2x screws and 1x wrench for mounting.
• 1x heat shield tape and 4 ties for protecting nearby components and legs.
• Carb kit: emulsion tube and three main jets (0.036", 0.037", 0.038") for tuning, and an F7TC spark plug.

Is installation difficult and does it require professional tuning?

Installation is straightforward for anyone comfortable unbolting the stock header and attaching a new one; the included wrench and gasket cover basic needs. You may want to adjust the carburetor with the supplied jets to optimize performance and avoid running too lean.

• Basic hand tools suffice for most installs; no welding required.
• Supplied jet sizes allow stepwise tuning—test one change at a time.
• Seek a professional tune if you lack experience with carb adjustments.

Who is this for: The HIAORS 212cc Exhaust Pipe Jet Kit is aimed at hobbyists and DIY mechanics who run Predator-style small engines on mini bikes, go-karts or utility equipment and want a durable, bolt-on header with basic tuning components. Choose this kit if you want a reliable replacement pipe that improves exhaust flow, produces a richer sound and gives you simple, included options to adjust fuel delivery after installation.
