With the E-Box system, Tecnigas has designed a racing exhaust system for original and 70cc sports cylinders. The length of the exhausts are optimised for these cylinders and thus allow full power performance. Hand-welded system with great character, capped off with a genuine carbon silencer. The internal construction of the expansion chamber and the subtle sound of the silencer make for a pleasant, deep sound and make it excellent on the road. E-certifified thus meaning the exhaust is restricted in the manifold and fully road legal. A removal of this restriction will invalidate the general operating permit (ABE) and significantly increase performance. Overall, the Tecnigas E-Box is a very good choice for those who do not want to change the cylinder kit or want to make significant tuning alterations to achieve an increase in performance. The main jet of the carburettor should be changed when fitting a new system.
