straight pipes?

I put hi-flows on my Pete, the jakes are actually quieter than the stock mufflers and I got .5 mpg better with them. If you want to run straights, go ahead, but don't post up later "Some Barney Fife busted me for making too much noise."

 

Kids .... they have to go through that stage. Eventually, they grow up. Eventually, they realize being able to hear quality music and hear the tones all the way through the range, and not end the day with dulled hearing is a "good thing", and better than that "sweet music" of racket. It's ok for a little while, but at some point you'll wonder what were you thinking about.

I've seen some straight pipe setups that sounded good and had an acceptable db level roadside, but then I've seen some that were very UNpleasant to anyone who had to travel adjacent them, to the point of being ridiculous. but to think "louder is better"??? That's just rude and only adds to the poor perception much of the public has towards truckers.

 

Me personally, I like the sound of 7" or 8" pipes with a press in muffler in the spool. They have a nice deep throaty sound on acceleration but are quiet while cruising and not obnoxious when the jakes are on, I don't like excessive noise, but I do like a nice tone

 

granted everyone has there own flavor.

but most don't want to hear the noise. the majority shouldn't have to move becuase one likes his noisy jakes.

 

Its free will. One can choose whether he wants nice loud pipes or not and one can choose to move because he doesn't like loud pipes. Everyone has choices.

 

not sure I agree with free will. you can carry free will over to weed burners.

 

I guess you don't care that you p i ss off other people around you or people in the towns that you enter with straights screaming off the jakes while slowing down coming into a town????

I like a little noise once and awhile also that is why I only have pipes on my scooter. But the truck, NO. I don't care to listen to it day and and day out and while trying to sleep at night when it is 15 degrees outside and you have to have it on high idle just to keep some engine heat to keep the cab warm.

I also like my muffled exhaust when coming into towns with no engine brake signs all over the place. I can still use my jakes and no one hardly knows.

Apparently you don't know as much as you think you do.

 

I live more then a mile away from the highway in a small town were truck traffic was minimal. It was not that big of a deal when a truck came through once a month during the day with straights. Now there is getting to be alot more traffic since there is alot less rail use and more truck use for the farm produce that is grown in our area.

When I signed the paperwork for my house ,20ish years ago noise was not an issue. Now it is getting to be an issue with the increased traffic. Why should I move and give up my house that I have been paying on for this many years so some dimwits can run overly loud trucks in our area????

Back when I did not know better, I took the muffler off my truck to get a free flowing exhaust in hopes of saving fuel and better performance. I soon learned that it actually hurt me because the turbo would not spool as quickly which hurt me. Put the muffler back on and it was back to a quicker spooling turbo and better actual off the line or bottom end pull.

When I was doing exhaust on cars and pickups, I learned that too much free flowing can actually hurt for every day driving were you are looking for more power down low rather then at the top of the rpm curve.

Same goes for Harley V twins. Better off the line performance is gained with a lesser flowing 2 into 1 setup then a free flowing open true dual setup. Now out on the open track, the higher reving motors that see very little low rpm, will benefit from an opened up exhaust.

Trucks run ultra low rpm and benefit from low rpm power more then high rpm power. So an opened up exhaust is really not helping much down low were we need it.

 

I understand what you're saying. I guess I was coming from working on diesel pickups where we needed the least amount of back pressure possible. I know on gas engines back pressure is needed on most applications.


I didn't mean the loud pipes in a bad way, it came off as that and I apologize.

If you look at it, it's a two way street. Or whatever the saying would be, basically you shouldn't have to hear the noise of the James but on the other hand they shouldn't have to put mufflers on just because people don't like them.

I understand the courtesy of it, and trust me, I wouldn't be one to go into a small town with my Jakes on. I also hate it when someone comes into the truck stop with their jakes on full blast. It's uncalled for. I for one would not run with my jakes until they're absolutely needed.

I think we can agree straights aren't too bad on 7-9" stacks but they're god awful on trucks with 5" or less stacks. Especially if you've got a Detroit under the hood.
