XIKOBY Mini Bike Center Rear Exhaust Pipe for Coleman CT100U — Stainless Steel, Shark‑Fin Tip

High-performance center rear exit exhaust pipe designed to replace stock systems on Coleman CT100U and compatible 98cc–79cc mini bike engines for improved clearance, style, and sound.

This XIKOBY central long-exit exhaust is a direct-fit replacement for a range of small four-stroke mini bike engines. Built from polished stainless steel with TIG-welded seams and a shark-fin styled tip, it repositions the muffler outlet to the center rear of the frame to increase rider legroom, reduce heat exposure, and add a sportier appearance. The kit ships with gasketry, hardware, a spark plug, heat-shield tape, and tie straps so you can install it with basic tools.

How does moving the exhaust to the center rear help when riding?

Placing the muffler outlet at the frame's center rear keeps hot components away from the rider's legs and clothing. That additional clearance lowers the chance of scuffs and burns while also preventing the pipe from contacting the frame during rough use. The result is a safer, cleaner riding space and a visually balanced rear end.

• Increased legroom reduces heat exposure to knees and pants
• Center placement minimizes contact with frame and bodywork
• Cleaner under-seat area improves maintenance access

Will this exhaust fit my mini bike engine model?

This XIKOBY pipe is engineered for commonly used small four-stroke engines, including Predator 79cc and 98cc, Lifan 154F, and factory-fit models like Coleman CT100U, GMB100, RT100, MB100 and several Doodlebug/Rascal variants. It’s intended as a replacement for the factory-mount exhaust; however, minor adjustments may be needed for non-factory frames or custom mounts.

• Compatible with Predator 79/98cc and Lifan 154F 98cc 4-stroke engines
• Direct-replacement for Coleman CT100U, GMB100, RT100, MB100 models
• May require small modifications on heavily customized frames

What performance or acoustic differences should I expect?

The upgraded outlet geometry and larger free-flowing path combine to slightly improve exhaust evacuation and create a more aggressive exhaust note. While this kit is not a guaranteed horsepower booster on every engine, riders typically notice crisper throttle response and a sportier sound. The shark-fin tip gives a visual cue to the more assertive tone.

• Freer exhaust flow for improved throttle response
• Deeper, louder tone without complex internal modifications
• Shark-fin tip designed for both looks and sound projection

What comes in the box and how durable is the construction?

The package is supplied with all essential mounting components and a heat protection solution so you can complete installation quickly. The exterior is polished stainless steel with TIG welds for longevity and corrosion resistance. A carbon-fiber style heat-shield tape provides secondary protection for nearby components.

• Includes exhaust pipe, gasket, spark plug, hardware, wrench, and ties
• Polished stainless steel body with TIG welding for durability
• Carbon-fiber heat-shield tape and steel ties for added protection

Who is this for: This XIKOBY center rear exit exhaust suits mini bike owners who want a direct-replacement muffler that frees up legroom, improves visual presence, and gives a more assertive sound without a complex installation. It’s ideal for riders with Coleman CT100U/GMB100-style machines or those using Predator and Lifan small four-stroke engines who want a durable, stylish upgrade that includes necessary hardware for a mostly bolt-on swap.
