Bought this tractor and it had no muffler so I bought one from Rural king today AC-4 by Stanley muffler, anyway, it came with 2 brackets but can't figure out how the support brackets work (I bought a muffler clamp to clamp everything together) the old support clamp is also pictured. My stand up pipe is just a little loose in the exhaust manifold, is that a problem?  Thanks, |

Not sure on 17s but on WD there was not a pipe in the manifold, the muffler went into the manifold, maybe later ones had a pipe in them, not a D17 expert or anykind of expert, just know enough to get myself in trouble. ------------- 1945 C, 1949 WF and WD, 1981 185, 1982 8030, unknown D14(nonrunner) |

The metal bracket on the left in your photo bolts into a threaded Hole on the outside of the exaust manifold and the two I believe the two brackets clamp around the bottom of the muffler with a mufler clamp. It is too dark outside to check right now. But yes the new aftermarket mufler does sit loose on the pipe and yes it does leak there. If you look down the mufler you can probably see straight through it from one end to the other. The two I bought both are a straight pipe inside the outer tube with holes in the inner pipe and they are fringing loud and useless. I want to get the serries 2 mufler and custom fit it onto my d17 and d15 I just haven't gotten around to trying it yet. So to answer you question loose fitting and poor performance is what I have found and I guess it is normal for the modern aftermarket parts. |

Series I D17 doesn't use a stand up pipe. Muffler goes directly into manifold. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| Well mine is still loose and leaks tried two different ones. Can't stand that mufler setup. Was thinking all summer I need to do something to quit it down. |

The original Nelson muffler worked better IMO but the whole setup is still chintzy. At least the Nelson muffler sounder better, lasted much longer and didn't let water into the exhaust. A threaded standpipe should have been used from the get go. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

You can weld a skirt around the bottom of the Stanley muffler that would do the same job as a Nelson but that is a pain. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Looks like part of the old muffler is stuck in the manifold - that is the pipe sticking up. You have to get that out before the new muffler can go on. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

It is a pretty heavy pipe that is attached to the manifold, I am thinking I will cut it off a few inches below where the hood goes over and then extend it above the hood and then put some automotive muffler on it... If I stick with a truck muffler I would think I would be safe as far as backpressure or does anyone have suggestions on non-stock mufflers besides it looks like crap and isn't the factory look. Thanks, |

| Look up the mufler used on the serries 2 and up 17. It is an oval shapes mufler and from what I have been told is decent. I haven't looked into what it will take to modify mine to take it yet but it is my plan. Then you don't have to worry about the looks department either it is just updated... not that I care quite is what I want. |

| I bought a series 1 D17 a few years back that had a pipe like yours up through the hood with a series 3/4 muffler mounted to it. Didn't look bad and it was quite, to quit for me..I like a little noise and ended up putting the correct style muffler back on it. |

| Put a pipe wrench on the tube thats sticking out of the manifold and see if you can remove it. The new muffler goes straight into the manifold. |
