Thats OK cause I am deaf in one ear already, actually it sounds great, originally I went straight pipe and it was to loud, NOW IT ACTUALLY SOUNDS LIKE A TRACTOR NOT A LAWN MOWER, improved power and better economy as well, would do it all over on the next tractor only I would do it sooner,I grew up in mid-Michigan on a farm in the 50's and 60's. You could always tell the farmers that had Farmall M's...they were the ones with hearing aids in both ears.
