My original exhaust rusted and broke near the lower end. I priced the original exhaust from MF and it was very expensive, after a quick search online I found this one for about 1/3 of the price which was delivered the following morning. I was pleased to find the new exhaust stack is of better quality and heavier metal than the original in my opinion. I did however have to weld a bracket onto the stack so that it mounts near the mirror of the tractor, just to be aware of this. I would highly recommend this product to anyone.
