Abstract: An exhaust piping system is provided for a vehicle with an internal combustion engine and an exhaust system including an emission control device. The exhaust piping system includes an exhaust pipe connected to the engine and an emission pipe connected to the emission control device. The exhaust and emission pipes include ends which are tapered to form reduced outside diameters. A flexible hose coupling includes a bore which telescopically receives the exhaust and emission pipe ends. First and second annular clearances are formed between the reduced-diameter pipe ends and the flexible hose coupling bore, which clearances reduce wearing and abrasion of the flexible hose coupling associated with vibration and relative movement between the pipe ends and the flexible hose coupling.
