Back in the 70's I had a neighbor who always took the muffler off his John Deeres and stuck a straight pipe on them because he liked to listen to them, not because he thought he was getting more power. He once did a dyno test on his 4520 with a muffler and then with a straight pipe and he gained one horsepower with the pipe. Then there's the old time IH mechanic who claimed all 806's needed a straight pipe because the factory muffler strangled them. My answer to that is, why would the factory spend hundreds of thousands of dollars developing and perfecting an engine and then strangle it with a 20 dollar muffler? I tend to think they are smarter than that.Jim
