For the last few years, we have lived close to highways. We understand that there will, always be some noise associated with traffic. However, There is no reason for straight pipes on trucks. We are talking about large trucks. Trucks that haul freight. I am about to declare war on large trucks, with straight pipes and Jake Brakes. If you are going to run Jake Brakes, get a muffler. These guys have no idea of how many people they irritate, with their noise. Let’s face it, most of them don’t care. That’s my point! It’s time to make them care! Notify your local governments, State Patrol, state government and Department Of Transportation, that you are sick of listening to the noise. Enforce and expand the “no engine brakes within city limits” ordinance. Make it state law, that mufflers are required for engine brakes.
