Motor Trend – Cheap vs Expensive Mufflers – Video

 

Muffler makes a difference when it comes to performance. What’s the real difference in power between mufflers that cost $40 each versus $100 each? What’s the power difference between a 2½- and 3-inch exhaust on a mild street engine that only makes about 350 hp? And is it true that “too big a pipe loses torque,” as you hear so often online or at the muffler shop? Every one of these questions from viewers gets solid, dyno-proven answers in this episode of as we run all the tests with a perfectly average, 350ci small-block Chevy using Thrush and Magnaflow mufflers.
