ABSTRACT:
A muffler for exhaust systems that feed exhaust into both ends of the muffler can. Exhaust gas enters into the muffler can where it enters an exhaust gas conduit that has a center plug installed. Exhaust is fed into both ends of the exhaust gas conduit. The exhaust gas is then forced out through a number of flared holes in the exhaust gas conduit, where it enters the muffler can and exits through an exhaust port. This design creates a longer exhaust flow path, which allows the exhaust gas to cool, extending the life of the muffler. Moreover, since the gasses are unimpeded in their flow through the conduit until they hit the partition plate, the exhaust conduit is less exposed to the full heat of the exhaust gas, unlike the cones, which do not penetrate deeply into the muffler can and bear the brunt of the exhaust gas.
