Why Briggs & Stratton Genuine Parts?

Only Briggs & Stratton genuine parts are specially designed to exact OEM standards, manufactured and tested to help deliver optimum performance in Briggs & Stratton engines. Not only are Briggs & Stratton genuine parts guaranteed to fit, but using them ensures that the Briggs & Stratton engine they are installed on complies with applicable (EPA) emission regulations and helps maintain valuable warranty coverage.

There are no substitutes when it comes to keeping engine powered equipment healthy. To maximize engine life, meet original equipment spec's and provide full warranty coverage, always use genuine parts from Briggs & Stratton.

Using non-original parts may seem OK based on looks, but they don't match up to genuine Briggs & Stratton parts in terms of performance and warranty-coverage. Use genuine parts to maintain good engine health from season to season.

Great replacement muffler
Great replacement part. My original muffler literally fell off the mower. I ordered the part on Saturday and it was waiting for me when I got home from work on Monday. It's just as good as the original.
