Independent testing with a dynamo test machine (volume 5, Number 1 of Secrets of Speed, July 1995) shows the original design mufflers (A5230ARORG, A5230ORG and A5230ORG/SS) increased power by 3.8 horsepower, or a 7.8% increase over the inexpensive muffler (A5230).

We strongly recommend purchase of #A5256E mu
