WalkerHeavy Duty 21039 Direct Fit Exhaust Muffler 2" Inlet (ID) 2" Outlet (OD)

Fit right up on my Long 510. It is slightly shorter than the one it replaced but that is good. My old one kept getting bent by low hanging branches so hopefully this one won’t. My manifold pipe is slightly smaller than the inlet of this muffler but a 1-7/8” clamp fit perfectly and was able to squeeze it down to a tight fit. About 1/2 the cost of online parts houses.

Did not fit easyI had to do some grinding and hammering

This muffler was the ideal, budget priced muffler for my Long 510. I bought thinking I was going to have to stretch it to fit, however the install was easy and a great fit.

Much better then the one that rusted off but seller needs to do a better job of listing the od and id of these mufflers. Not the size I thought i was getting. Made it work though.

Works great and sounds good! Installed on an old Wisconsin 4 cylinder

The inlet is 2" with slits. You can't expand it. I had to have an elbow expanded to fit over the inlet and then rather than clamp, I welded it together. Had the pipe going into it been 1 3/4 inch, it might have fit. The original muffler inlet (same pt. #) was flared.

fit my tractor perfect.

Exactly what I was expecting.

Fit a '73 White tractor and sounds fine.

Product not all as great as advertisedCould of gotten a cherry bomb for half the price and same quality!

Didn't reduce noise at all , just a expensive straight pipe , you see right through it .Would not recommend it !

The muffler was ok but the exhust pipe was not 2 1/2 inches so it cost me for adapters
