The internals in my old round muffler rusted out and I decided to replace it with a 200 style Stanley muffler. It is much quieter and I think I can ditch my ear protectors now! Happy so far, have to get it out in the field to know for sure.  ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

| Nice looking unit— we replaced the strait pipe that was on the 200 with that muffler a few years ago. Made the tractor much more comfortable to run, still a little loud under a load where you may need hearing PPE. Lost a little whistle off the turbo, but did not notice any hp decrease. I’ll bet that tractor is a head turner in the field! |

The turbo started leaking last year and I replaced it (Lloyd Made turbo) that had a loud whistle at 1900 RPM and higher. Made it a pain in the ears to run. My brothers straight pipe is pretty loud, can't imagine Allis thought that was a good thing. It was $80 so I should easily get that amount of satisfaction out of it. ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

That most certainly is an AWESOME looking XT !! May I ask what you do with it that the "pipe" was a little "loud" for your liking  ?

If you see Charlie on a straight pipe XT that’s mine lol. His has always had a muffler on his, don’t know why he doesn’t like the straight pipe. Maybe it’s because of all the ringing I have in my ears. Can’t bring myself to muffle that sweet 301 music. I know I should. Charlie, I guess I need to drive yours to see if I can bring myself to try one. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

If it's like any other Stanley muffler, I would rather have the straight pipe with the turbo whistle! It also hurts the turbo's performance as well by restricting air flow. ------------- '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 |

Yes I don't work it much in the Field but the times I do use it, I got annoyed by the whistle. Much happier now, I doubt I will notice any performance decrease. Sadly, most of the paint bubbled on it after 30 min. Time to strip it and apply High Temp Paint. ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |
