A Muffler That Flows Better Than a Straight Pipe?!? We Have the Flowbench Test Results

For decades, the classic “straight pipe” has been the hotrodder’s go-to exhaust modification to pull maximum horsepower from their engine. But the reality nowadays is, modern mufflers can flow even better than a traditional straight pipe. Better yet, you get all that airflow without the noisy racket of a non-muffled exhaust! Don’t believe us? We went to MagnaFlow to see it firsthand, and learn some airflow science along the way. On the MagnaFlow flowbench, we witnessed one of its perforated core, straight-through mufflers exceed the flow of a standard three inch piece of exhaust tubing. Wait until you see the results!
