I have a new OHV 13hp Briggs motor iIam installing in My elburro. The oem muffler and pipe is too tall. JC Whitney has a universal chrome cycle muffler that has a 1.5" inlet and overall is 12" long. The dimensions are good for my frame and the look would be nice. Would this muffler be too free flowing for my 13hp Briggs? Id rather have a cycle looking muffler than a lawn tractor looking set up.
