This video also applies to the Bobcat 642, 643, 645, 742 and 743B machines with a similar setup. Installing an aftermarket muffler / exhaust system and flex pipe kit. I do not recommend the brand I installed due to the sloppy construction and the fit was very bad and had to be modified. However, it was cheap compared to extinct Bobcat OEM parts so here is the link to buy the same kit, but don’t say I didn’t warn you. This kit is specific to the 743 and 743B with serial number 501911001- later.
