Exhaust TECNIGAS E-Box for Derbi GPR50 -2009, Aprilia RS50 -2010 (D50B0)

With the E-Box system, Tecnigas has designed a racing exhaust system for original and 70cc sports cylinders. The length of the exhausts is optimised for these cylinders and thus allows full-power performance. This hand-welded system has great character and is capped off with a genuine carbon silencer. The internal construction of the expansion chamber and the subtle sound of the silencer create a pleasant, deep sound, making it excellent for road use.
