Quite simply the best exhaust on the market for the HM, but not to be put on just any configuration! Hand-welded rolled, magnificent finishes, very racing sound.
 

 
We recommend it on a powerful kit such as MALOSSI MHR TEAM or REPLICA 80cc, POLINI EVOLUTION 80cc, TPR 80cc aluminum ... Diagrams 128/190 Minimum, diameter 49mm, also works very well on long races (85cc ...).
 

 
Clearly a large kit with large driagrams with a carburation in 25 to 30mm. This ultra light exhaust will offer you a maximum of torque, acceleration but also top speed!
 

 
It has a machined aluminum silencer with molded end caps. Very high fashion but with a high price all the same!
 

 
Mounts on HM DERAPAGE RR 11, CRE, CRM ... 50
