Hp Corse is an Italian exhaust brand that always makes sublime silencers, as it were true design pieces!
For example, the Hydroform, repeatedly copied by competitors but never equaled.
The Evoxtreme and the GP07 have now been added.
Judge for yourself about these masterpieces of Italian craftsmanship.
