   2 friends have MC-7s with 8V71s with dual vertical pipes on the rear of the bus.
   One has a small resonator on each. This bus is extremely loud when under a load and always louder than I would want.
    The other one is dual straights stacks with no resonators or mufflers. This bus is OBNOXIOUSLY LOUD!!. He started it at a bus rally to show someone his new "cool" exhaust system. We could not carry on a conversation inside another bus parked approx. 75-100 feet away.  If he had revved it up one more time, he would have probably been threatened with bodily harm by several people parked near his bus. This is the type of behavior that what gives busnuts a bad name.  Jack

I'm glad you started this Jack because I wanted to say the same thing.  We've got an unmuffled 6-71 in a big forklift.  When they are using it in the summer I can hear it scream a mile away.  2 stroke Detroits need mufflers.  End of story.

I had an old Reo I cut the mufflers off of & drove it about 6 months. I didn't care what anyone said because I COULDN'T HEAR ANYBODY TALKING.... (say WHAT?..... WHATDIDCHA SAAAAAY????? Speak UP son... I CAN'T HEAR YOU!!!!!) DDs need mufflers. You can get by with the turboed versions but they are still loud.

Personally speaking-there is no such thing as a too quiet vehicle.  Plus, a Detroit makes a lot of engine noise-which is good music! Good Luck, TomC

I'm young enough to appreciate loud pipes and old enough to want quiet. Tough spot!  ;)LOLOL
I put cutouts in my exhaust on my '56 Chevy so if I want to tease people at a show or give the "kids" a kick, I can open them up for them inside the car. Ya might want to think about that!
  But I would say - without a doubt - quiet would be my first choice.
 
  I seen a coach or two with "tasteful" stacks out the back. That interests me. Do any of you think there is an advantage to getting the exhaust up and away from others on the ground???

When I first had the 8V92TA put in my Eagle it just had a straight pipe. It sounded great, especially when I turned the Jakes on., but I had to add a muffler after a few weeks. It was just toooooo loud.

LOUD pipes save lives ;D

Interesting thought, but I don't hear the loud stuff coming, I only hear it leaving.

& another thing, If you are sitting on the loud pipe machine, you can't hear danger coming (my car is quiet  ;D ).

I used to like loud until I grew up  ;D

It seemed to me that the faster & classier bikes & cars at the drag strip usually had mellow tone pipes. Mine did & always drew a crowd of admirers, not bad for a '82 cutlass that was all there down to the A/C & street tires (7.20 @100mph in 1/8 mile).

You are right, that was a very quick car. I had a stack of time slips over 2" tall of 7.20 passes. After a while, you get used to it & you start doing stupid stuff on the street (like racing motorcycles, new vette's & those german sports cars). So I sold it before I lost my D.L. or life.

Was fun for a while. . .

Oh, the rear gear was 2.7 to 3.3   The car didn't like too much & would slow down with more than 3.3

Loud pipes saves lives if on a motorcycle as most people don't see a motorcycle and if they do they tend to ignore them.  I have loud pipes on my Harley and very quite pipes on everything else.
Please watch out for motorcycles as most of us are decent people.

Like I said before, I only hear the loud pipes as the bike is leaving, NOT approaching, so how does that save any lives? That combined with the fact the bike rider with loud pipes can't hear danger approaching leads me to believe the claim 'loud pipes save lives' is bogus, made up by people wanting to make lots of noise. Is there any good proof that I'm wrong? The constant on headlight is starting to loose its efectiveness now that everyone has their lights on. But the light is still better than noise.

Those loud pipes are really annoying. Do you really think it is a good idea to annoy idiots that can't drive well to start with?

I do watch out for bikes. What I notice is that most bike riders obey the laws & set great examples for highway courtesy.

I have also noticed the rogue idiot that lane splits, rides in the blind spot of cars/ trucks, & overtakes traffic with alarming speed. It is this idiot that is so easy to remember & thereby leaves a bad image for all bike riders.

This from one who loves most of the racket music a piston engine makes.

Kyle:
Funny I can hear the loud pipes comming as well as going.  You are right also that, as in all instances, there are a few idiots that leave a bad taste in everyones mind, be it bikes, cars, trucks, boats, big trucks,  and yes even buses.  Thanks for watching out for bikes.  Yes it is proven, can not qute the statiscits but loud pipes do save lives on bikes.  I can hear a bike before I can see it most times and some of the quiter bikes sneak up on me.  Lets face it bikes are realitive small in comparison to cars and trucks.
Lets all drive safe and therefore be safe.
