Crossover Muffler

摘要

A performance-enhancing crossover muffler for internal combustion engines includes an enclosed case having an inside, and two inlet pipes located inside the case having respective inlet ends extending through a frontside of the case for connection with two outside engine exhaust manifolds, and respective interior ends which merge together to define a merge entry. The muffler also includes one or more outlet pipes located inside the case with outlet end extending through a backside of the case for connection with an outside tailpipe, an interior end defining a merge exit, and one or more apertures in the outlet pipe communicating with the inside of the case. The muffler further includes a piping merge zone between the merge entry and the merge exit for commingling exhaust flows from the two engine exhaust manifolds. The two inlet pipes and the piping merge zone are without communication with the inside of the case.

主权项

1. A muffler for increasing engine performance while attenuating acoustic noise in a vehicular exhaust flow, comprising:
an enclosed case having an inside; two inlet pipes located inside the case comprising:
respective inlet ends extending through a frontside of the case and adapted for connection with two outside engine manifold exhaust pipes; andrespective interior ends opposite the inlet ends merging together to define a merge entry; at least one outlet pipe located inside the case comprising:
an outlet end extending through a backside of the case and adapted for connection with an outside tailpipe;an interior end opposite the outlet end defining a merge exit; andat least one aperture in the outlet pipe communicating with the inside of the case; and a piping merge zone between the merge entry and the merge exit for commingling exhaust flows from the two engine manifold exhaust pipes, wherein the two inlet pipes and the piping merge zone are without communication with the inside of the case.
