exhaust -NARAKU- crossover clear coating/yellow-carbon for GY6 139QMB/QMA

Most 4-stroke exhaust systems are simply borrowed by the manufacturers from the 2-stroke series and only the mounts were adapted. The result is then a visually appealing system with mostly worse performance values than the original exhaust.

The Crossover allows the currently upper limit of power development in GY6 50cc engines through an exhaust system due to the tuned internal structure. This makes it one of the most powerful systems for these engines.

This system is painted clear, with real carbon muffler in yellow-carbon. This gives you a pure racing look as known from YASUNI and Co from the 2-stroke range.
