Perfect fit
Its only been on for a week so I cant comment on how long it will last but it fit perfectly on my briggs and stratton motor on my zero turn

Perfect fit
Wasn’t sure what to expect, but the part came earlier than promised, and it is excellent quality. Bolted directly to the engine without any fuss, and the flanges were perfectly flat and in alignment. Made for an easy install. Mower sounds great and much quieter as well.

Works GREAT! But it needs the muffler extension to be 100%
After adding a small extension piece, this is working fine. Without the extension, there was a tendency for backfires. APPLICATION: Bad Boy ZT Elite, 60". I re-engined from a blown Kawasaki 740V to a B&S Intec 24HP. The old muffler did not fit. This one did. It was less cost. It works fine!

Fit perfect
This exhaust assembly was recommended with my purchase of a 27 hp b&s. It fit perfect. It doesn't come with gaskets which you will need. Luckily I had a few different sets to work with. Fired up the engine and it sounded quieter than the replaced 25 hp b&s, imagine that! Very satisfied with this product. Fit the gravely pro turn 60 zero turn mower the same as original. Very happy customer with a new 27 hp b&s plus new exhaust. It's great to repower expensive equipment yourself. ... show more

Great muffler!
Fit like a glove! Did not even have to modify my zero turn to make it work!

Poor Customer Service and bad parts
I will never purchase anything from this vendor. Amazon's website said this muffler would fit the Briggs and Stratton engine I purchased that fit a John Deere mower. It didn't fit, I returned it and got charged a restocking fee. I should not be charged a restocking fee if their product isn't correct or fit and recommend for the engine I purchased. I am a prime member, so much for benefits. ... show more

Installed on vertical shaft 27hp Briggs
All the mounting holes lined up perfect but you’re going to need to purchase hardware and gaskets separately. I ended up using 5 bolts that were 5/16-18unc thread and 3/4” long with thick washers and a lock washer. The support hole on the engine needed to be drilled out slightly larger and tapped for the 5/16 bolt. This muffler is effective and decently built but don’t expect to run the engine for long periods of time without ear protection. ... show more
