Losi DBXL 2.0  non silenced  , will only fit the New 2.0 version of the DBXL,
Designed around the chamber dimensions of the popular race winning Olimat Engineering Losi 5b pipe . Using the same mount position as the original DBXL V1 pipe of the rear  diff support this balances the pipe and makes it easy access to battery  by removing the mounting bolt and simply lifting the pipe up.
