The 6 Best Brigg quiet mufflers (2023 reviews)

It is an exact replacement for the Ariens 46" mower with 20hp b&s engine. It fits perfectly, inbolt old and install new muffler in reverse order, and definitely much more quiet than the old blown out muffler. The mounting screws cut threads in the muffler, so require moderate torque to start them, and snug them up.

The new muffler is easy to install and it fits perfectly. The OEM has screws that mount the muffler to the frame. The muffler mounts to the tractor frame and then you have to insert the exhaust pipe into the muffler and then attach the exhaust pipe to the engine head. These resist the bolts loosening up.

Why We Like This:

Easy install, less than 10 minutes
15 minutes and machine runs quiet and well
Perfect fir for a craftsman courage 20 hp motor
Takes about 5 minutes or less to do the replacement

The exhaust tone is not as high pitched and poppy anymore, and it's a considerable amount more quiet.

The muffler fits and works fine. It's definitely better than having a straight pipe but it's still pretty loud and will break apart. The exhaust port on your motor is larger and unthreaded. It is easy to go to 1" with a regular npt bushing.
