The invention relates to a device and a process for making connections that cross over exhaust devices, particularly pipes connected to catalytic cases, audible catalytic cases and silencers. The device is characterised by the fact that it is essentially made up of a drum (1) for mounting parts (2) to be machined, at least one mobile assembly (3) of centring (4), flow drilling (5) and flow tapping (6) units for said parts (2) to be machined and a structure (7) to support and guide the assembly drum (1) in addition to at least one mobile assembly (3). The invention is particularly suitable for use in the manufacture of tubular parts, specifically in the automobile industry, and even more specifically exhaust devices, including pipes connected to catalytic cases, audible catalytic cases and silencers.
