XIKOBY Central Rear Exhaust Pipe Kit for Coleman CT100U/GMB100 — Polished Stainless Steel, Shark‑Fin Tip, Improved Leg Clearance

The XIKOBY Central Rear Exhaust Pipe Kit replaces the stock outlet with a center-mounted, stainless steel exhaust that improves leg clearance, resists corrosion, and adds a sporty shark-fin tip for a louder, more aggressive sound.

This bolt-on kit is engineered for popular small four-stroke engines—Predator 79cc/98cc, Lifan 154F 98cc, and OEM equivalents used on Coleman CT100U, GMB100, Realtree RT100, Massimo MB100, Baja Doodlebug DB30 and similar mini bikes. It shifts the exhaust exit to the frame center rear to reduce heat contact with rider legs and clothing while delivering a finished, performance-oriented look and a richer exhaust note. Built from polished stainless steel with TIG welds and supplied with mounting hardware, the kit aims to be a durable, visually striking upgrade that’s straightforward to install for mechanically inclined riders.

How does the central rear exit change rider comfort and safety?

Relocating the exhaust to the center rear increases legroom and moves hot components away from where the rider’s legs and clothing usually sit. This lowers the chance of burns and avoids contact that can damage fabric or the vehicle frame. The supplied carbon-fiber heat-shield tape adds extra protection at the pipe-to-frame interface.

• Center-mounted outlet creates more clearance for rider legs
• Heat-shield tape resists high temperatures and reduces radiant heat
• Reduced contact risk with frame and clothing

Will this kit fit my Coleman CT100U or similar mini bike?

The kit is designed as a direct replacement for engines commonly used in CT100U and GMB100 models, including Predator 79cc/98cc and Lifan 154F 98cc 4-stroke engines. Compatibility depends on your bike’s header flange and frame mounts; most users with the listed models will find the included gasket and hardware fit without modification.

• Compatible with Predator 79cc/98cc and Lifan 154F 98cc engines
• Fits Coleman CT100U, GMB100, Realtree RT100, Massimo MB100 and similar
• Gasket and mounting hardware included for straightforward installation

What are the construction and durability features of the XIKOBY exhaust?

Manufactured from polished stainless steel and assembled with TIG welding, the pipe resists corrosion and mechanical wear better than untreated metals. The surface finish improves aesthetics and eases cleaning, while precision welds increase structural longevity under vibration and heat cycling common to small engines.

• Polished stainless steel resists rust and discoloration
• TIG-welded seams increase durability under stress
• Shark-fin tip provides a distinctive end-cap that withstands road exposure

How does the shark-fin tip affect performance and sound?

The specially shaped shark-fin tangent tip is styled for a sportier look and tuned to alter the exhaust note, producing a deeper, more assertive sound. While gains depend on the whole intake/exhaust setup, the tip is designed to help exhaust flow and give a more aggressive auditory presence when accelerating.

• Shark-fin tip enhances visual sportiness and road presence
• Alters exhaust tone for a richer, louder sound
• May improve flow characteristics when paired with an optimized intake

Who is this for: The XIKOBY Central Rear Exhaust Pipe Kit is aimed at mini bike owners who want a safer, cleaner-looking exhaust route with a more aggressive aesthetic and sound. It suits do-it-yourself mechanics and hobbyists with Predator or Lifan-based 79–98cc 4-stroke engines used in Coleman CT100U, GMB100, and comparable models who want a durable stainless upgrade with included mounting hardware and heat protection.
