Straight pipe 7040?

Hey guys, Just curious if anyone here runs a straight pipe on a 7000 series with the 426? Is it a lot louder? I want to hear a bit more turbo whistle and wouldn't mind it being a bit louder, As long as it isn't unbearable. Would there be any issues with a straight piped 7040.. would I lose any power or harm the engine? 

I love the sound of an awesome running straight piped diesel.....for about 5 minutes from a distance on somebody else's tractor and farm. I'd never want to do that to my ears continuously.

Our d21 has straight 5" loud and can hear it a mile away.
I wear plugs but if it was more than a toy we would run a muffler.

I have a 4" on my 7040 and 5" on my 7060 and 7080. I wouldn't have them any other way! I love the sound and in the cabs its not much of a difference.

I have to agree hearing is one of those things you don't notice getting worse till it is too late

I have a 3" pipe on my 7060 and had a muffler on my 7050. I couldn't tell any difference inside the cab. I have a 5" on my 7030 and it is a lot deeper tone than the 3". I think the 5" with a cab wouldn't be bad.

I have a straight pipe on my 7010 and 7060. I also had one on a 7040. Not much difference in the cab as said before. The 7060 had a real good whistle to it until I had to have the turbo replaced. I love to here a good sounding straight piped diesel. All of them have 3 inch pipe.

The hours per year you need to sit in the seat has a lot to do with it too I would think. Like Lonn said above, just a little bit louder is still louder. When you're exposed to a frequency for a long time, it takes it's toll, and for every decibel louder that frequency is, the more quickly it leaves its mark. I hope to hear my grandkids someday, even after "all I've been through". The high pitched constant whine at work here is enough for me.

Ran a D21 for a few years, loved the sound but did wear hearing protection.  When I was younger I would even open the door on my M2 for a few minutes just to listen to the motor, now that I am older I think I am paying for it.  Protect your hearing as much as possible.

Used to run my brothers Farmall M with a straight pipe now I wear a $6,000.00 pair of hearing aids

Running a straight pipe will usually drop exhaust temps 100 degrees or a little more, which is good for the engine. If you simply remove the mufflers two internal baffles, you can keep the noise level down and drop exhaust temps as well. Use a piece of pipe three feet or so long and 1 1/2" diameter. Set the pipe on the shop floor and slide the muffler down over it. Pound the muffler up and down like a fence post driver until the first baffle is broken loose. Turn muffler over and pound out the other baffle. Result is cooler exhaust temps and pleasant noise levels. I used to do this to many brand new tractors and the Customer never even realized it.

I put one on my 7010 last year before bailing and I don't think it's any louder than the muffler was. It is about the same height as the cab I don't know if that help's and I like the visibility better.

I bought a late 200 with factory cab. Came with a straight pipe. Had to run it 7 miles down the road. Went to town and bought a muffler put it on before tractor came home. I hope your cab is good, you will wish it was before the day is over.

Amen to that.  The pipe on my 6080 is the same height as the top of the cab.  It is not loud inside the cab.  On the outside you can hear that thing coming from a mile away at wide open throttle.

my 7010 and 7080 both have straight pipes, and I don't hear any dif in noise inside the cab, but my old lady.....ooooops....I mean the loving wife says both sound sweet!
