FVRITO 28mm Exhaust Muffler For 50cc Bikes
The FVRITO 28mm Exhaust Muffler is designed to replace stock units on most 50cc, 110cc, and 125cc Chinese dirt bikes, as well as QUAD ATVs and dune buggies. It uses an aluminum body and has a mounting hole distance of 28mm (1.1 inches). The overall length is 244 mm and the width is 85.5 mm. This compact design aims to improve exhaust flow while keeping weight down, which can help throttle response in urban trails and light off-road riding.
It ships with a clamp and gasket, making installation straightforward on compatible models that use a 28mm header. The lightweight aluminum construction offers good heat resistance and weather durability, reducing corrosion over time. Riders often report a deeper exhaust note and a modest performance improvement on smaller displacement engines when upgrading from a factory muffler.
HAUERTZX 28mm Exhaust Muffler Kit
The HAUERTZX 28mm Exhaust Muffler Kit is a full modification package compatible with a broad range of 50cc to 125cc dirt bikes, including CRF50/70, XR50, Taotao DB10/DB14, Baja Xpro, Apollo, Rocketa, TTR, SSR, and Coolster models. It features a 28mm head and an eye-to-eye measurement of about 45mm, making it a solid match for many header pipes.
Described as a complete exhaust upgrade with no need to buy additional parts, the kit is crafted from quality metal designed to resist heat, melting, and rust. The color options—red, silver, and black—also offer a styling choice for riders who want to customize their bike’s look. Installation is intended to be straightforward on compatible Chinese pit bikes.
HIAORS 32×24.5mm Exhaust Gasket Pack
HIAORS offers a 5-piece crush gasket set sized 32×24.5x5mm, designed for 50cc through 150cc dirt bikes and ATVs. The gaskets fit a long list of models such as SSR Razkull, Tao Tao DB-14, Hellcat, Apollo RFZ, Piranha, Lifan Xpro, Boom Vader, and more. The precise 32×24.5x5mm dimensions aim to deliver a reliable seal under engine vibration and heat cycles.
These gaskets are well suited for pit bikes and four-wheelers seeking a durable seal during maintenance or upgrades. Using the correct gasket size helps prevent exhaust leaks, maintain backpressure, and protect engine performance over time. They’re a practical option when you’re rebuilding or upgrading exhaust components and need dependable sealing areas.
Sporacingrts 26mm Exhaust Muffler
The Sporacingrts Black Exhaust Muffler features a 26mm mounting hole and measures 244 mm in length with a width of 83 mm. The build uses two materials—aluminum and steel—to balance weight with durability, making it suitable for a range of 50cc to 125cc dirt bikes and Chinese pit bikes. It is designed for direct replacement, simplifying installation and requiring no separate instructions.
As a 26mm option, this model helps riders who need a snug fit with existing headers while still offering a noticeable exhaust note enhancement. The mixed-material construction aims to resist heat and wear in off-road conditions, supporting longer service life under typical riding conditions. It’s a pragmatic upgrade for riders who want a straightforward swap with reliable performance gains.
PRO BAT Falcon Bull Style Exhaust System
PRO BAT’s Falcon Bull Style Exhaust System is a full pipe and muffler upgrade designed for 50cc, 70cc, 90cc, and 110cc dirt bikes, go-karts, ATVs, and dune buggies. The overall assembly runs about 710 mm long, with the pipe itself around 510 mm and the muffler about 200 mm. The muffler diameter is roughly 80 mm, and the engine mounting hole distance is about 45 mm, indicating a larger, more aggressive setup than slim 28mm kits.
Properly installed, this system can improve exhaust flow and top-end response on small-displacement engines. It’s intended for riders who want a bold look and a pronounced exhaust note, and it comes with the necessary hardware to mount on compatible machines. As with any aftermarket system, verify compatibility with your bike’s exhaust port and frame clearances before purchase.
Buying Guide
Choosing a 50cc dirt bike exhaust involves balancing compatibility, durability, and performance benefits. Start with fitment: measure your header pipe diameter and the mounting hole spacing to ensure you select a 26mm, 28mm, or 32mm system that matches your bike. Common sizes on many Chinese dirt bikes are 28mm and 26mm, with some kits offering a 32mm option for larger displacement engines or specific models. If you are unsure, opt for a kit that lists broad compatibility or provides clear compatibility charts for brands like Taotao, Coolster, SSR, Tao Tao, Apollo, and similar pit bikes.
Durability and materials matter for off-road use. Aluminum mufflers are lighter and resist corrosion, while steel variants can offer extra strength but may require maintenance to prevent rust. Look for products with heat-resistant coatings or protective wraps to extend life in dusty or muddy riding conditions. Ease of installation also saves time; kits including clamps, gaskets, and clear mounting instructions reduce the likelihood of leaks or alignment issues.
Performance gains from a muffler upgrade on a 50cc bike are typically modest but noticeable. Riders often report a crisper throttle response, a deeper exhaust note, and slight improvements in low- to mid-range torque. For top-end improvements, pairing the exhaust with a properly ported manifold and a well-tuned carburetor can yield the best results without sacrificing reliability. Always check that the exhaust does not interfere with the chain, swingarm, or brake lines, and verify that it remains compliant with local noise restrictions.
