Budget mufflers. What do you get for $40? How do they sound and how much power do they kill? On this episode of Engine Masters presented by AMSOIL, we run our 408 Cleveland with 12 different muffler options, including no muffler, straight through, chambered, and turbo style. Which one is best for you is up to you, but here's all the info you'll need to make the decision.

Well, maybe. This time on Engine Masters, presented by AMSOIL, we dive into what effect changes to your intake manifold's plenum volume will have on your motor. We want to know if all of the Internet's theories about big boost, big cubes, and/or big rpm needing bigger plenum volume really hold water. Will all of that increased volume really turn into increased power production or are you just creating hood clearance headaches? Watch as we go from straight out-of-the-box to out-of-the-bounds-of-sanity with this plenum volume comparison.
