Universal 1.5-2″ Inlet Hexagon Exhaust Muffler
The Fast Pro Universal exhaust muffler is designed to fit pipe diameters from 38mm to 51mm, making it a flexible option for a range of dirt bikes, street bikes, scooters, ATVs, and quads. The unit ships as a complete pipe and muffler with hardware, though installation instructions are not included.

TianDiPRO 28mm Exhaust Muffler For GY6
The TianDiPRO exhaust pipe and muffler are tailored for GY6 125cc/150cc ATVs and similar four-wheelers. The system measures about 710mm in total length, with engine-mount hole centers around 48mm. This configuration aims to deliver a reliable upgrade for riders seeking a balanced sound and performance boost without extensive modifications. Always verify that the mounting holes and pipe diameter match your ATV’s specifications before installation.
AlveyTech Muffler & Pipe Assembly For Coleman AT125-EX
The AlveyTech exhaust pipe and muffler assembly is designed for the Coleman AT125-EX ATV, offering a full-length 29-3/4″ setup with a 1″ pipe and a 3″ muffler diameter. The matte black finish and spark arrestor provide corrosion resistance and improved aesthetics. This option emphasizes durability and a direct fit for Coleman models, reducing the need for extensive adjustments during installation.
PRO BAT Exhaust Pipe+ Muffler System
The PRO BAT system is marketed for 50cc to 110cc engines, including Falcon Bull-Style quads. It features a full-length package with a 710 mm total length, a 510 mm pipe, and a 200 mm muffler. The pipe flange diameter is approximately 32 mm, and mounting hole spacing is around 45 mm. The design emphasizes a robust build and straightforward installation for compatible small-displacement ATVs and go-karts, making it a practical upgrade for riders seeking improved exhaust flow and sound without major retrofits.
ICONSPORTSS 38mm Exhaust For 125cc-250cc
The ICONSPORTSS 38mm exhaust system is designed for vertical 4-stroke engines in 125cc–250cc class ATVs, dirt bikes, go-karts, and buggies. It features a standard 38mm inlet, aiming to improve airflow and sound while offering a discreet upgrade path for common pit bikes and ATVs. Users can expect enhanced low-end torque and a more pronounced exhaust tone, with compatibility that covers a broad spectrum of 4-stroke, vertical-engine platforms.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Verify bore diameter, engine displacement, and exhaust inlet size (38mm vs 28mm) to ensure a proper fit for your ATV model.
- Installation practicality: Some exhausts ship with complete hardware; others require additional mounting brackets or installation instructions. Check your toolset and whether welding or additional brackets are needed.
- Durability and materials: Look for corrosion-resistant finishes (e.g., matte black or stainless steel) and robust hangers to withstand off-road conditions.
- Performance goals: Upgraded exhausts can improve throttle response and low-end torque, though gains vary by engine and exhaust design; more aggressive tones may affect noise levels and require local compliance checks.
- Compatibility breadth: If you own multiple small-engine off-road vehicles, a universal 38–51mm inlet can offer flexibility, but ensure critical mounting points align with your ATV.
- Regulatory considerations: Some regions limit aftermarket exhaust noise; always confirm local noise and emissions rules before replacement.
- Cost-to-benefit: Compare the price against expected gains in power, sound, and weight; heavier setups may dampen performance on small-displacement engines.
- Maintenance: Choose designs with accessible spark arrestors and cleanable cores if you ride in dusty or muddy environments.
For riders seeking a practical balance between fit, durability, and performance, these options provide a spectrum from universal adapters to model-specific assemblies. Always cross-check your ATV’s user manual and consult with a professional if you are uncertain about compatibility or installation requirements.
