Tractor just started getting LOUD
2014 Cub Cadet LTX1050 w/24hp Kohler Twin
Last 2 times I've mowed, exhaust note has gotten noticeably louder. Exhaust doesn't sound normal...higher pitched, kinda "poppy". Also seems just a little down on power, especially under more load.
While idling, I set the parking brake, got off, opened the hood, and found exhaust seems to be leaking around the area where the muffler/manifold bolts to the head (passenger side). I replaced the exhaust gaskets (they were worn out), still loud. Doesn't seem quite as down on power, but can still feel it under a load.
Muffler looks OK, no rust, no visible holes or damage. Kinda stumped.
Like new condition, only 156 hours. New plugs & fresh oil change at start of this season. Compression is great.
Possible muffler is shot? Maybe where the muffler pipe is welded to the manifold flange. I must be not seeing something.
