D6D straight pipe

D6D hot rod?

[@jasonlangley8112]

Sitting in my work trucking balling my eyes out. For my whole life my daddy was a dozer operator. I can close my eyes and re live my youth. That dozer sounds great!!!

[@subathasansivathasan6082]

One of the best sounds I have heard in so many Cat dozer videos. Good job in keeping it well maintained

[@sweatlodgegarage8195]

I love the sound of that turbo winding out.

[@sandcobra]

i would keep like that . so my neighbors would think i had a panzer tank.

[@leetime454]

That thing sounds exactly like an old army duece and a half.

[@cat977loader]

Great video, love that straight pipe sound D6 looks like it's been well maintained.

[@johnnyholland8765]

If you take away the turnout and run it straight with a rain cap most of the noise goes straight up. That is the sound of CAT power. Don't mess with it. JHolland

[@guod118]

Music to my ears!

[@powellvalley]

I think it sounds pretty good too. I just figured you'd hear more of the turbo whistle than that with it bein straight piped.

[@dennislaws5187]

My dad bought a 933 G and a 955 H in the 60s both had straight exhausts no mufflers from Cat. loud as hell every day 8 hours.

[@rowdyropp7464]

Sound good with that temporary straight pipe! Love these older Cats they really are reliable equipment. But they do have their little quirks. Have fun cleaning the belly pans off of her. Nothing like getting your ass all greasy but shes worth it!

[@joecorrie1]

nice to see someone let a machine idle for a few seconds before shutting it down, even when his video is waiting on him .

[@grantpeterson2987]

I thought the exact same thing. Every time my boss is done with a piece of equipment, be it a skiddy, trackhoe, whatever, he leaves it wide open and kills it. When I hear that, I just wanna puke.... And the same thing on a frosty cold morning, when he cranks it over, once it hits on the first sign of firing, that throttle gets slammed wide open and off to work he goes.

[@buildzmodz3871]

​@grantpeterson2987 lmao yup I had a few bosses like that, they don't give a shit just gona get another machine eventually anyways lol

[@hoghunter0825]

Sounds like my 01' Peterbilt 378 Setout truck , its straight piped and i can set 6 loads out in an hour in the woods with good wood. sometimes i can get 8 an hour dependin on how the boys in the woods are workin ... btw , the dozer sounds sick

[@stanpatterson5033]

Sounds fine listening on the video. Obviously the pipe is loose. I would turn it so the outlet faces forward and is not spewing noise and exhaust towards the operator.

[@johnnyreb360]

Love that exhaust note. Ear plugs are cheaper than a muffler. ❤

[@TRuEGaMingPS3]

Sounds like a 6bt cummins and boy does it sound good

[@Chief176]

Keep pushing brother! Great sounding machine!

[@ronaldkirk9685]

That still is an awesome machine👍💪

[@lukethekanefan]

thats got some serious torque there boys

[@luketui5035]

nice turbo sound mate.....

[@dshmechanic]

Sounds awesome, and props to you and your family for keeping her in such nice condition....just goes to show that these things go forever with proper maintenance. Do you happen to know what year this one was made? If I had to guess just by looking at it I would say mid to late 70's?

[@catmandoo2148]

Yes too loud needs muffler. normally I dont say that but if your going to run it all day you need a muffler. these d6d's were the best d6 made.

[@randytd260807]

i prefer this old school D6 in front of any new D6

[@jonnewell1994]

sounds great:) expecially the whine in the motor:)

[@dieseltrainfreek]

The only way a D6D must sound 5 Star :-)

[@Firebird_876]

Sounds great with the strait pipe on there.

[@Gmiller0907]

Yeah buddy! Let 'er breathe. You'll have increased power and fuel efficiency.

[@lucasandrey1385]

Que barulho desse motor slc mto top👏👏👏👏

[@earlhayes2969]

Sounds Awesome even better with Headphones on

[@regsparkes6507]

Turn the pipe towards the front, or make it higher to clear the ROPS, then most, ( but not all ) of the sounds will be defleced away from you. Still, I'd wear those Ear Plugs though. This is a nice size of Cat, it does sound good, but not for all day working.

[@iansimpson1285]

Reg Sparkes Is

[@mathman1923]

leave it a straight pipe. Sounds great.

[@jamestruitt3393]

Hearing protection please!!!!! Don't wanna go deaf with that sweet sound!

[@regsparkes6507]

+James Truitt You have a good pount here. That beautiful Cat sound AND the tubo whine will hurt your ears after a few hours on this great Cat.

[@kramnull8962]

It is just hard to leash the sound of torque at work these days. What is this world coming to?

[@jayarmstrong3848]

Not long enough cooldown before shutdown

[@TRuEGaMingPS3]

Sounds like my truck. Second gen cummins

[@timmerrox12]

[@cumminsfan]

sounds good!

[@Billy982810]

the first thing we did was take the muffler off.

[@EthanCollier01]

Nice whistle

[@amosmccoy116]

sounds awsome

[@justinhughes5887]

After a while it prolly get old just put a 3" silencers on it ther round.

[@josh33025]

First dozer I ever ran was a d6 like this.

[@patrickgambsky6290]

Nice machine ❤

[@erichansen82]

Nice

[@TrainboyRR]

i love the video

[@darinkurtz1024]

sounds good but a little loud I'd put the muffler back on it maybe it would stop premature cylinder head wear

[@rockdawg1467]

Darin Kurtz naw that wont hurt it ran a 977 with no muffler didnt hurt it none just loud

[@sitatan]

Good machine, well minded. However, if you ever want amazing, get a KOMATSU.

[@splitdoctor1993]

[@B422TMack]

That 3306 Cat motor sounds good . I Did the same thing to a D6D LGP W/Hyster winch my granddad had When i was 18 yrs old . by the time i stright piped it. the other operators let me have the ole D6D . we cleared a lot of land & built a many pond & lake w/ a D6D . NICE MACHINE !!!

[@seananderson2949]

sounds good

[@localcrew]

Nice rake. I like 'em quiet though. I'd probably like it with a muffler on it better. That's just me though.

[@killthebums]

the beauty of a straight pipe is it isn't permanent, when I'm doing long hours of work I have the silencer on and when I want to show off I get my straight pipe lol

[@redtussock]

Dude ... yer might wanna learn to speak up ... and exactly what did you achieve with your 1 Gallion of diesel matey.

[@justinhughes5887]

Well worry bout turbo if gonna get back on with in the half hour leav it runin but it'll cool while it's of. Is it realy getting that hot while low rpms I dnt think.

[@killingoldgrowthsince]

If the exhaust doesn't melt the brim of your hard hat, it's safe to shutdown.

[@todlindley8101]

Yeh I could listen to that all day no probs just needs clamping for side exit position, nice nice D6D, Bullet proof n last a lifetime

[@jasonbooth5141]

Sounds good

[@justforever96]

Sounds great! Gotta love that turbodiesel sound. Although I agree with the guy below; no reason not to turn the angled tip so that it faces the front. It'll reduce the noise at the operators hear drums a lot. If you've ever heard the difference between firing a gun from behind it and from beside it (never tried being in front of one yet!), you know that the sound impulse goes directly out from the opening. It's much quieter standing behind a gun than beside one. And on aircraft, when they have exhaust exiting one side, you can hear the difference clearly when the oping is facing away from you and towards you. It's good to hear someone sitting on a Cat admit that a Komatsu can actually do something better. The level of fanboyism among Cat fans is astonishing, so it's nice to hear someone who can take an objective view of the facts.

[@randymaylowski2485]

nice video of that :) and nice bulldozers :)

[@brandonhersey197]

thats bad ass straight pie on a cat d6d
