LiiQuu 1.5" Exhaust Conical Stub Spark Arrestors Pack of 2 — Steel, Low-Restriction Fit for 1.5" ID Off-Road Pipes

The LiiQuu 1.5" Exhaust Conical Stub Spark Arrestors are a pair of steel, plug-in inserts designed to reduce emitted sparks while preserving exhaust flow for off-road motorcycles and ATVs.

These compact conical spark arrestors fit common off-road pipes and slip into 1.5" ID outlets to provide a lightweight, durable barrier against hot particulate ejection. Engineered for compatibility with a variety of dirt bikes and select ATVs, the arrestors are made of steel and intended to be less restrictive than many packed-style screens so you can maintain throttle response while meeting spark-control needs on trails.

Will these arrestors fit my exhaust system?

They are made to fit pipes with an inside diameter of 1.5 inches and an outside diameter of about 2.2 inches, and stand 4.4 inches tall. The product is sold as a pack of two, so you’ll have a set for dual-exit systems or a spare for future installation.

• Inside diameter: 1.5 inches — intended insertion size
• Outside diameter: 2.2 inches — pipe clearance guide
• Height: 4.4 inches — overall length to accommodate internal chambers
• Package: 2 x stub spark arrestors — one pair included

How do these arrestors affect exhaust performance?

The LiiQuu conical stub design aims to block sparks without creating the heavy backpressure of dense mesh or packed arrestors. Because they are constructed from steel with an open conical profile, they tend to be less restrictive and help preserve midrange throttle response compared with more restrictive designs.

• Conical profile reduces flow restriction compared to packed cores
• Steel construction balances durability with minimal added weight
• Intended for aftermarket systems like FMF Powercore 4 and similar outlets

How easy is installation and maintenance?

Installation is straightforward for most slip-fit exhaust outlets: the stub pushes into the pipe and can be secured per your muffler’s existing hardware or by using clamps where appropriate. Maintenance requires periodic inspection and cleaning; remove carbon buildup to preserve airflow and check for any deformation after heavy use.

• Plug-in stub fits 1.5" ID pipes — minimal tools typically required
• Steel body wipes or brushes clean carbon buildup effectively
• Lightweight design makes removal and replacement quick on the trail

Who is this for? Riders and weekend trail users who need a simple, durable spark-control insert for 1.5" exhaust outlets will find these LiiQuu arrestors useful. They suit owners of compatible Honda CRF models (CRF230, CRF450, CRF250L), Yamaha YZF426 and TTR125 riders, Kawasaki KLX230/KLX230R/KLX125/KX450F users, owners of FMF Powercore 4 systems, and Can Am Outlander riders seeking a compact, less restrictive steel arrestor. If you require certified forest-service spark arrestors for regulated areas, confirm local acceptance; these arrestors are intended to reduce spark ejection while maintaining practical exhaust flow for off-road performance.
