6" Exhaust Extension Stock (DUB213)

The six-inch exhaust extension stock is a customizable muffler extension that lets you extend the exhaust outlet on a wide range of small two-stroke engines.

It fits most engines in the 0.29 to 0.80 cu in two-stroke range and accommodates most mufflers. The extension stock can be cut, drilled, tapped, and welded, giving hobbyists a flexible option to tailor length, fit, and installation for their project.
