Abstract
An integrated manifold, muffler, and catalyst device for an engine uses perforated ducts surrounded by a resonator volume. Exhaust flow is routed from the exhaust ports by the ducts to a close coupled catalyst. The combination of the perforated ducts with the resonator volume and close coupled catalyst reduces exhaust flow restriction while at the same time increasing catalyst performance and reducing noise emissions.
