PACEWALKER Slip On Muffler 38-51mm Universal
PACEWALKER’s Slip On Muffler offers a titanium alloy body with a stainless steel connector, providing a durable, heat-resistant shell for sport and street bikes. The removable DB killer lets riders tailor sound from quiet to more aggressive as desired. With an inlet range of 38-51mm and an overall length around 365mm, this universal slip-on fits many motorcycles, scooters, and some dirt bikes. The combination aims for easier installation and a sharper exhaust presence, balancing performance and everyday practicality for riders who want noticeable sound without sacrificing reliability.
Because it uses a universal fit, installation may require clamps or adapters and a cautious check that exit clearance and heat shields are not affected. The titanium alloy body reduces weight and resists heat, while the stainless steel connector enhances durability against corrosion. Riders can expect a more pronounced exhaust note without excessive drone at cruising RPMs. Compared with OEM cans, the PaceWalker unit typically delivers crisper throttle response and improved gas flow, though results depend on engine displacement, exhaust routing, and other aftermarket parts.
POSENG 38-51mm Universal Slip-On Exhaust
POSENG’s 1.5-2 inch inlet exhaust muffler is a universal slip-on designed for a wide range of street and sport motorcycles, scooters, dirt bikes, and ATVs with 38-51mm pipes. The 400mm length provides a noticeable but manageable presence, delivering a deeper, confident tone when the DB killer is in place and a sharper edge when removed. Crafted from titanium alloy with a stainless steel seal, it offers corrosion resistance and durability for daily riding. Its fitment is broad, making it suitable for many models that use 38-51mm pipes while allowing tone customization to suit different riding styles.
Installers should verify 38-51mm compatibility with their pipe and check for clearance around mounting points and the braking system. The titanium alloy body minimizes heat transfer and weight, while the stainless connector resists rust. The DB killer provides versatility for track days or daily riding, balancing volume with neighbor-friendly levels in street use. A universal slip-on like this can enhance throttle response and exhaust flow, but true gains depend on overall exhaust routing and engine displacement.
PACEWALKER Grilled Blue Universal Slip-On
PACEWALKER’s Grilled Blue Slip-On combines a titanium alloy body with a distinctive blue gradient finish achieved through a double-head baking blue process. The unit uses a stainless steel connector and a removable DB killer, offering the same universal 38-51mm fit as PaceWalker’s standard slip-on. At 365mm in overall length, it balances under-seat clearance with a more pronounced exhaust tone. This model emphasizes aesthetics as well as performance, making it a popular choice for riders who want visual appeal alongside a sportier sound and easy installation on common 38-51mm pipes.
Sound and installation notes mirror the standard PaceWalker exhaust: the titanium body preserves durability, the DB killer can be left in for comfort or removed for a louder edge, and the 38-51mm range keeps it broadly compatible with popular street and sport bikes. The blue finish adds style, while the overall length and mounting points are designed for straightforward mounting with common exhaust clamps. Overall, it blends visual flair with practical performance for riders seeking a presentable, moderate-volume upgrade.
ICONSPORTSS 35mm Exhaust Head Pipe for Street Sport Bikes
ICONSPORTSS presents a 35mm exhaust head pipe built from 304 stainless steel, delivering durability, corrosion resistance, and a long service life. The head pipe is designed to fit 150cc-250cc vertical engines commonly found in dirt bikes, scooters, and street sport bikes, offering a reliable path for a muffler upgrade. This unit emphasizes corrosion resistance and solid construction, aiming to extend the life of the exhaust system even in challenging conditions. Installation requires standard mounting points and clamps, making it accessible for riders performing a DIY upgrade.
The 304 stainless steel keeps heat in check and resists rust, while the 35mm bore helps improve flow compared with stock headers. Fitment varies by motorcycle, so users should verify engine type, pipe diameter, and clearance with the muffler they plan to install. This head pipe provides a dependable path to a louder, crisper exhaust note when paired with a compatible muffler, delivering a balanced upgrade for street- and sport-oriented builds.
YYCKE 28mm High Performance Exhaust Kit
YYCKE’s 28mm high-performance exhaust kit targets 90cc-125cc dirt pit bikes, including models like CRF50, SSR Baja, Coolster, and Tao Tao variants. The kit features a 28mm head pipe with a muffler, plus mounting hardware such as a metal clip, gasket, and screw kit. The design aims to improve appearance and performance, delivering a more stylish look and improved exhaust flow. The kit’s straightforward installation mirrors typical aftermarket upgrades for compact displacement bikes, requiring basic hand tools and standard clamps for a practical, budget-friendly upgrade path.
Included parts provide a complete upgrade path, with a 1 x Exhaust Muffler, 1 x Exhaust head pipe, 1 x metal clip, 1 x Black rubber gasket, 2 x gaskets, and a screw kit. While designed for popular 28mm systems, fitment should be checked against the motorcycle’s exhaust diameter and mounting points. The kit offers an affordable route to a balanced blend of improved flow, a more aggressive tone, and a cleaner look that complements smaller, sport-oriented builds.
Buying Guide
Key factors to consider when choosing a sport bike exhaust include fitment, sound, material quality, and installation ease. Start with the pipe diameter on your bike (usually 38-51mm for universal slip-ons) and confirm the inlet of the muffler you’re considering. Removable DB killers offer flexible tone—useful for track days or neighborhood riding. Material choice matters: titanium alloys save weight and resist heat, while 304 stainless steel provides robust durability and corrosion resistance. Consider the overall weight impact, as lighter systems can improve handling and throttle response.
Sound preferences and local regulations should guide your choice. A louder setup may enhance on-road presence but could trigger noise restrictions or neighbor complaints on stable, daily commutes. Look for a complete kit or kit-compatible components if you want a clean install with gaskets, clips, and clamps. Check for clear installation instructions and compatibility notes from the manufacturer, as fitment can vary by engine type and mounting points. Finally, weigh value against durability and warranty, especially for universal slip-ons used across multiple bikes.
For riders prioritizing aesthetics, features like gradient blue finishes or polished stainless surfaces can complement bike styling. If you ride different bikes, universal 38-51mm options offer versatility, but always verify the pipe size and clearance to avoid heat shield interference or exhaust grounding. Consider also future upgrades: some systems pair well with other aftermarket parts, preserving a cohesive look and sound profile across your sport bike lineup.
