my 7010 has a short pipe, only about 1-1/2 ft above the hood and then curves to the side. I did this because I was in near a bunch of low tree branches that like to break pipes off. and it worked well, no extra noise inside the cab, so I left it that way. I can hear a small amount of turbo with it this way...but not bad. the turbo eats a lot of the exhaust noise.

Interesting topic. We put a 4" curved pipe on our 7045, it's awful in the cab, right at pto rpm it has a terrible low tuned hum in the cab, almost like you are sitting in a tuning fork. I've never figured out why. Sure sounds nice on the outside! But you won't last long inside! We put the muffler back on, kinda bummed about it. Doesn't make any sense.

did you try curving the pie to the front? also put your foam blocks back in under the dash, that will help a lot.

The dash is full of foam, and I did try pointing the pipe different ways, didn't make a difference. It's a wierd one. Lol

The cab is resonate at that engine RPM. Apparently there is a low frequency sound component in the exhaust note. I doubt foam will help. Try changing the length of the exhaust pipe

Carl, go with a 3" or 5" pipe it will cut down on the resonance of the engine. I have a 5" on my 7060 and at about 1600rpm it does the same thing. Speed it up or slow it down and it quits. The 5" is great at pto speed. It is a curved pipe facing to the right as I'm in the seat.

OK, would be worth a try. I know I tried the 3" off our 1486 and that seemed to cut it down a lot. I did have the curve facing the right. I always bumped it up higher in rpm range, but kinda feel bad making er scream when it does need to be haha

Hey all,
I wanted to drag this thread back up to see where everyone in this thread is buying their straight pipes. Please tell me: Where you got it What size Rough cost and if you are pleased with the quality. I am looking at Shoup, and they want more for a straight pipe than they do a muffler. I am also eyeing a 40 dollar ebay special chromed curved straight pipe that does not look too bad. All of them I am looking at are 3 inch, I was planning on just mounting direct to the elbow. The bigger pipes are intriguing, but IDK how a guy would make those fit. Any input appreciated, Thanks! |

My son built a 3" exhaust that exits under the side panel and follows the lines of the cab . No pipe in your view and a little louder in the cab , but ear plugs are a good trade to have an open view over the hood . This is on a Maroon 7060 .Dropped the precleaner below the hood to clean that up too . Has anybody tried putting a spiral/auger section in your straight pipes ? Was told this is a trick truckers do with their straight stacks .

I'm 51, and have worn hearing aids for 2 years, thanks to spending my youth on 100 hp open station tractors (190XT with factory straight pipe, 200 with muffler doing tillage work). I also spent a great deal of time inside a sow farrowing house. About 2 of the worst things a young kid can do. I also had a piece of sl*g burn a hole in my ear drum 3 years ago. 70% loss in that ear and 30 in other. Take care of your selves early on.
Having said that we have an 8050 with the muffler eliminator and original stack. Listening to the tractor in the seat with door closed sounds no different than our other 8050 or 70. But get 50' away from it while it's working and it sounds deep and strong, like it bellows. Also have 7020 that I put a 3" resonator inside a 3.5" straight pipe to help with visibility and that is no louder than the muffler. Leon B MO

Here is where I got the eliminator for the 8050. They have a pretty good selection of pipes. Leon B MO

I just went to a local muffler shop for the straight pipe on my XT. I brought the turbo elbow and they cut a length of pipe to my request and then flared it to fit nicely over my turbo elbow - 3" pipe. Total cost: $30. Paint it black with high temperature paint and you are good to go. Don't buy anything off e-bay. Support your local businesses. |

This is a matter of personal opinion, and in my opinion they sound like chit without a muffler. My bro has one with a straight pipe (7010) and while it is true there is not much difference in the cab, there is a big difference if you are 50 feet away. I'd much rather listen to my 7040 with a muffler. Just one man's opinion though.

My brothers XT has muffler, mine has a straight pipe. There is no doubt mine sounds better, especially under load. But his is much easier on the ears. A set of ear plugs still allows me to hear the music of that sweet 301 but you can hear me a half mile away lol. I have had multiple people tell me they love hearing her run in the field but have no idea how I stand it in the seat. 4’ straight pipe with a rain cap. Its personal preference, to each his own. |

Hey GM guy,
Got my straight pipe at a local exhaust shop. 3 inch plain steel 4 feet long. $20 cad Just clamped it right on the elbow. Sounds nice, but I wear earmuffs if I am in it all day
