    I keep that truck out of Co, well anywhere but Alaska from now on, but Mt never gave me any grief, or checked it.

    Montana has gotten bad since the oil field slowed down. When the boom out east took off they closed some of their older scales and ended up putting more people in pickups out roaming around. Now that it has slowed all of those roamers have to justify their jobs I guess.

    I see said the blind man. The last time I was in Mt was 3 or 4 years ago, and I went down the east side into Id.
    That was kind of an outlaw trip, here to Ok, 16 miles north of the Tx line and besides the yukon scales, never went through another open scales, except blew one in Id and stopped at one in Ok.

    What will get you is the Jake noise. People running straight pipes is why you have all those "no Jake brake" areas. I've got good mufflers on my FL Classic, and the Jake is quiet.

    Also, a lot depends on what engine you have. We have a 379, 3406b with straight pipes and it really isn't that loud at all. A N14 Cummins with straight pipes is much louder, especially the Jake.

    Years ago I had a old single axle IH with 250 Cummins and straight pipes. That thing would make your ears bleed, because it didn't have a turbo to help quieten it down. Old 2-stroke Detroits we really loud too, even with mufflers.

    LOL Try a 2 stroke jimmy with straights if you want noise, you don't even need to use the jake.
    My 3606 E is loud, but nothing like a cummins, but there is not near as much jake there either .

    BC Cummins motors had "boom" around 1750-1850,( I think, been a while) right where the motor is happy, and with straights, it's downright annoying.

    Yes common sense. Lots of signs stating no engine brakes etc. Through small towns, why rattle all the windows? Especially in the middle of the night. Its called "keeping a low profile " or not attracting unnecessary attention. I am not against straights, but when approaching a lot, rest area, where drivers are resting why wake everyone up? Some guys are their own worst enemy.

    I love the sound of a V-12 Detroit with straight stacks....on somebody else's truck, and from a distance.
    My truck...I want it quiet.
