Abstract

An exhaust device (1) for internal combustion engines (2), having a main catalyst (3), an auxiliary catalyst (4), and an exhaust manifold (5) connecting the input of the main catalyst (3) to the exhaust outlets of the internal combustion engine (2), so as to feed the exhaust gases from the exhaust outlets to the main catalyst (3); the exhaust manifold (5) assuming a first operating configuration connecting the input of the main catalyst (3) to the output of the auxiliary catalyst (4), and the input of the auxiliary catalyst (4) to the internal combustion engine (2), and a second operating configuration connecting the input of the main catalyst (3) directly to the internal combustion engine (2) and excluding the auxiliary catalyst (4).
