XIKOBY Center Exit Exhaust Pipe Kit for GMB100/CT100U Mini Bike — Polished Stainless, Shark-Fin Tip, Heat Shield

XIKOBY’s Center Exit Exhaust Pipe Kit replaces the stock rear pipe on GMB100/CT100U-style mini bikes to free up legroom, add a sporty central tail exit, and deliver a more aggressive sound with durable stainless construction.

This compact exhaust assembly is engineered as a direct-fit replacement for a wide range of 98cc–79cc 4-stroke mini bike engines and frames that use a center rear exit. It combines polished stainless-steel finish, TIG welding, a shark-fin styled muffler tip and a heat-protection package to improve durability, appearance and rider comfort without complicated modification.

Will this fit my Coleman CT100U or similar mini bike?

The XIKOBY kit is designed to suit Predator 79cc / 98cc and common clones used in CT100U-style mini bikes, including FR* GMB100, Massimo MB100, Baja Doodlebug DB30 and others listed. Fitment is typically plug-and-play for frames with a central rear exit; minor adjustments may be needed on some aftermarket mounts.

• Compatible engines: Lifan 154F 98cc 4-stroke, Predator 79/98cc, and like-for-like clones.
• Frames: Designed for mini bikes with a central rear exhaust exit like Coleman CT100U/GMB100.
• Includes hardware: gasket, lock washers, nuts, wrench and steel ties for installation.

How does the center exit design improve comfort and safety?

Central rear routing moves the exhaust away from the rider’s legs, lowering the risk of burns and reducing interference with pant cuffs or scuffs to the frame. The orientation also offers a cleaner rear profile and better ground clearance for low-slung frames.

• More legroom: exhaust outlet clears foot/leg area to prevent contact.
• Heat control: included carbon-fiber heat shield tape adds thermal protection.
• Frame protection: fewer contact points reduce wear and accidental frame damage.

What performance or acoustic changes should I expect?

The kit’s redesigned muffler tip and internal flow path are tuned for a sportier tone and a modest increase in exhaust scavenging efficiency. While not a power miracle, the shark-fin tangent tip can sharpen throttle response and produce a more pronounced, satisfying exhaust note for recreational riding.

• Acoustics: deeper, more aggressive roar without extreme decibels.
• Efficiency: smoother exhaust flow may slightly improve throttle response.
• Visual impact: polished stainless and shark-fin tip for a race-inspired look.

What materials and parts come with the kit?

The kit is built from polished stainless steel with TIG-welded joins for corrosion resistance and longevity. A comprehensive hardware set lets you install the pipe and add a secondary heat barrier to nearby components immediately after fitting.

• Construction: polished stainless steel body and TIG welds for durability.
• Included parts: central rear exhaust, gasket, spark plug, heat shield tape, lock washers, nuts, wrench, and steel ties.
• Heat shield: carbon-fiber tape included to protect frame and clothing from residual heat.

Who is this for? The XIKOBY Center Exit Exhaust Pipe Kit is aimed at mini bike owners and hobbyists who want a cleaner rear layout, improved rider comfort, and a sportier sound without extensive fabrication. It’s ideal for Coleman CT100U and compatible GMB100-style machines, restorations, custom builds, or anyone replacing corroded or damaged stock exhausts with a durable, visually upgraded component.
