POSENG Titanium-Alloy Slip-On Motorcycle Muffler 400mm Grilled Blue with Removable dB Killer — 38–51mm Inlet, Corrosion-Resistant

POSENG's 400mm slip-on motorcycle muffler is a universal titanium-alloy silencer with a 38–51mm inlet and removable dB killer for adjustable sound and corrosion resistance.

This slip-on muffler is engineered to fit a wide range of street bikes, dirt bikes, ATVs and scooters that use 38–51mm exhaust pipes. Built from titanium alloy and stainless-steel components, the grilled blue finish delivers a multilayer color gradient while resisting rust and wear. The unit ships complete with mounting hardware and an integrated, removable dB killer so you can tailor exhaust tone to your bike and local rules.

Which motorcycles and pipes will this muffler fit?

The POSENG muffler accepts inlet diameters between 38 and 51mm, covering many small- to mid-displacement street bikes, off-road machines and ATVs. It's a slip-on design so it mounts over the existing mid-pipe or tailpipe where clearances allow.

• Inlet compatibility: 38–51mm adjustable clamp range
• Length: 395–400mm overall, suited for compact to mid-length exhaust layouts
• Common applications: dirt bikes, scooters, small sport bikes, ATVs
• Slip-on installation minimizes permanent modification

How does the removable dB killer change sound and use?

Removing the supplied dB killer produces a louder and sharper exhaust note, typically preferred on higher-displacement setups. With the dB killer installed, the muffler offers a deeper, more subdued tone that aligns better with noise regulations and neighborhood riding.

• Installed: quieter, deeper tone for compliance and daily riding
• Removed: louder, more aggressive sound for track or off-road use
• Easy access: dB killer is removable without altering the muffler body
• Best practice: check local noise laws before removing

What materials and finishes does the muffler use, and why does it matter?

The outer shell is crafted from titanium alloy with stainless-steel components at the inlet and mounting areas. That combination reduces weight, resists corrosion, and keeps the unit looking fresh despite heat and exposure.

• Titanium alloy body for lighter weight and heat tolerance
• Stainless-steel inlet and fittings for durable clamps and joins
• Grilled blue baking finish yields a four-color gradient for visual impact
• Frosted surface treatment reduces glare and shows fewer fingerprints

How difficult is installation and what’s included in the package?

Installation is straightforward for a typical slip-on swap if your bike has a compatible pipe and accessible mounting point. The muffler arrives with the necessary mounting hardware to secure it in most common configurations.

• Slip-on type—no welding required for most fits
• Package includes: 1 muffler, built-in dB killer, clamp and mounting accessories
• Length: 395 mm (about 400 mm) for fit planning
• Recommended: basic hand tools and a torque wrench for clamp tightening

Who this is for: Riders who want a lightweight, stylish slip-on muffler that balances looks, performance and adjustable sound. Choose this POSENG muffler if you need a universal 38–51mm inlet option with corrosion-resistant materials and an eye-catching grilled blue finish.
