This RC-scale aluminium muffler is supplied as a single-piece unit intended for Kyosho motorcycle kits and compatible scale platforms. It is an aftermarket cosmetic upgrade that replaces the usual plastic or pressed-sheet exhaust with a solid aluminium assembly for a more authentic scale look.
Targeted at hobbyists pursuing cosmetic tuning, the KM388 is focused on finish and fit rather than altering power characteristics. At installation check the exhaust flange and mounting points on your chassis, align the pipe with the header and use original fasteners or equivalent model-grade screws to secure it. Minor trimming of body mounts or bracket tabs may be required to ensure a neat fit.
Being aluminium, the unit increases local durability and will change the mass distribution slightly on the model; consider small suspension or balance tweaks when dialling in handling characteristics.
Fit the KM388 when you want a tougher aluminium visual upgrade for Kyosho-scale bikes, and confirm clearance and torque settings to protect model mounts.
