XIKOBY CT100U Exhaust Header for CT100U/GMB100 Mini Bikes — Polished Stainless Steel, Center-Rear Exit

The XIKOBY CT100U Exhaust Pipe Header Kit is a polished stainless-steel central rear exhaust assembly engineered to replace stock pipes on CT100U/GMB100-style 98cc mini bikes for improved clearance, heat control, and a sportier look.

This complete header kit is designed as a direct-fit replacement for a wide range of small four-stroke mini bike engines used in Coleman CT100U, F-RP GMB100 and equivalent models. Built from TIG-welded stainless steel with a center-rear exit, the assembly aims to keep hot components away from rider legs, reduce heat transfer to the frame, and give your bike a cleaner, more aggressive profile. The package includes mounting hardware and a carbon-fiber heat shield tape so you can install it quickly and add a second layer of thermal protection.

How does the central rear exit improve rider comfort?

Routing the exhaust to the center rear of the frame moves the hot outlet away from the rider’s legs and common contact points. That reduces the risk of accidental burns and limits heat exposure to clothing or nearby components.

• Center-rear placement increases legroom and reduces direct heat near knees.
• Heat dissipates away from the frame to minimize heat damage.
• Included heat shield tape provides an extra protective layer.

What materials and construction features make this durable?

The primary pipe is treated stainless steel with precision TIG welds to resist corrosion and mechanical wear. A polished finish improves corrosion resistance and gives a refined appearance that lasts through weather and riding conditions.

• Polished stainless-steel body resists rust and discoloration.
• TIG welding ensures stronger, cleaner joints for longevity.
• Heat shield tape resists high temperatures and abrasion where needed.

Will it fit my mini bike and what comes in the kit?

This header kit is made to fit many 79–98cc 4-stroke mini bike engines used in Coleman CT100U, GMB100, Realtree RT100, Massimo MB100 and similar models. The kit bundles all necessary hardware so you can replace the stock pipe without hunting for adapters.

• Central long pipe sized for Predator/Lifan 154F 79–98cc 3.0hp engines.
• Package: pipe, carbon-fiber heat shield tape, spark plug, gasket, lock washers, nuts, wrench, and steel ties.
• Designed for bolt-on installation with included fasteners and gasket.

How does it change my bike’s look and sound?

The sleek polished finish and rear-exit layout give the mini bike a cleaner, sportier silhouette that stands out on the trail or street. While not marketed as a performance muffler, repositioning and pipe design can produce a fresher, more assertive exhaust note compared with worn or stock routing.

• Polished surface adds a premium visual upgrade to the frame.
• Rear exit visually balances the bike and emphasizes a sporty stance.
• Pipe geometry can slightly alter exhaust tone for a sharper sound.

Who is this for: The XIKOBY CT100U header kit suits owners of Coleman CT100U and compatible mini bikes who want a durable, direct-fit pipe that increases legroom and reduces heat exposure while improving the bike’s appearance. It’s ideal for hobby riders, restorers, and anyone replacing a corroded or poorly routed factory exhaust with a ready-to-install stainless-steel assembly and hardware.
