SHIQINHA 1.1in Slip-On Muffler Universal 28mm Exhaust Silencer for 50–125cc Pit Bikes & ATVs with Heat Shield

SHIQINHA's 1.1 inch slip-on muffler is a universal replacement silencer designed to fit many 50–140cc Chinese 4-stroke pit bikes, ATVs and select minibikes, providing quieter exhaust and improved low-speed response.

This compact, slide-on exhaust silencer was built to be a straightforward upgrade for CRF50-style pit bikes, 110–125cc ATVs (Tao Tao, Coolster, Apollo, SSR and similar), and some minibike frames with minor modification. Constructed from metal and aluminum with a reinforced clamp and included heat-shield tape, the assembly aims to balance durability, noise reduction and simple install for weekend riders, hobby mechanics and small-gasoline engine projects.

Will this muffler fit my bike or ATV?

The SHIQINHA 1.1 inch muffler fits many Chinese 4-stroke 50cc–140cc pit bikes and 50cc–125cc ATVs that accept a 28mm (1.1") slip-on outlet. It is listed compatible with popular models such as CRF50, SSR 110/125, Tao Tao and Coolster series, but some models require minor alignment or mounting adjustments.

• Intended inlet diameter: ~28mm (1.1").
• Common compatible brands: Tao Tao, Coolster, Apollo, SSR, X-pro, Kazuma, Baja.
• Mini bike fit possible (Predator 212/196cc) with bracket modification.
• Not compatible with some model-specific frames (check model fit notes).

How does it affect sound and ride characteristics?

Designed as a silencer, this muffler reduces harsh, high-frequency noise and produces a deeper, more controlled exhaust tone. The internal structure creates moderate backpressure that can improve low-end torque feel at slow speeds without major tuning changes.

• Noise profile: deeper, less piercing exhaust note.
• Performance effect: subtle low-speed torque optimization.
• Not a high-performance expansion chamber; meant for quieter, reliable operation.
• Sound reduction varies by engine type and pipe routing.

What materials and hardware are included, and how easy is installation?

The muffler is made from durable metal and aluminum components with a reinforced exhaust clamp to prevent loosening. It ships as a slip-on unit with the necessary clamp hardware and heat shield tape so most installs require only basic tools and minimal mechanical experience.

• Construction: metal/aluminum body with corrosion resistance.
• Included: exhaust clamp, mounting accessories and heat shield tape.
• Install style: slide-on; simple clamp tightening required.
• Minor modifications may be needed for some minibikes or unusual frames.

Is the muffler durable enough for off-road use?

SHIQINHA uses robust metals and a reinforced clamp to withstand typical wear, dirt and vibration from trail and pit use. The finish resists scratches and corrosion, and the supplied heat tape protects nearby components and riders from hot surfaces.

• Durability: built for rough conditions and frequent use.
• Corrosion resistance: aluminum and treated metal finish.
• Safety: heat shield tape reduces burn risk on exposed pipes.
• Clamp reinforcement prevents loosening under vibration.

Who is this for? This muffler is for riders who want a straightforward, durable replacement silencer that tames aggressive exhaust noise and adds modest low-speed responsiveness without complex tuning. It's ideal for owners of CRF50-style pit bikes, 110–125cc Chinese ATVs, hobbyists modifying minibikes, and anyone seeking an easy-install slip-on silencer with heat protection and reliable hardware.
