Walker Quiet-Flow SS 22266 Direct Fit Exhaust Muffler 1.5" Inlet (ID) 1.5" Outlet (ID) for INFINITI QX60

Used this as a new replacement 1.5" muffler on a repower of a 35hp Briggs Vanguard engine. So far a very economical replacement and a lot quieter than stock one from Briggs and Stratton at 75% savings over OEM. Nice snug fir onto a 1.5" exhaust pipe inlet and outlet. Hopefully will last as this engine produces enough heat to turn the stainless muffler a rainbow color instantly at full throttle. Probably a 25% reduction in decibels over stock muffler. Have bought 2 and am very pleased so far.

I have purchased and installed several of these mufflers for use on small engines (up to 2000 cc). The engines have had one (1) two (2) and four (4) cylinders. The muffler did a very good job of quieting all of them. On each installation I welded shut the drain hole. It is necessary due to the way I am using the device. The muffler is located close to the engine and reaches over 400 degrees F in only about two (2) minutes so condensation is not a problem.Several people have said that these mufflers are not Stainless Steel... they are wrong. These mufflers are made from 409 Stainless which is very magnetic like the whole 400 series of stainless's. It appears that when most people think about Stainless steel they think about alloys in the 300 series where most of them are not magnetic.It should be noted that stainless steel can RUST under the right conditions. This muffler Can Rust under certain conditions also, but even then the corrosion will be orders of magnitude less than plain steel, galvanized steel, or even aluminized steel. The best thing that you can do to reduce corrosion is to locate the muffler close to the engine so it heats up fast and avoid starting the engine and shutting it down before the muffler has become hot enough to drive off all of the moisture which contains acids from the combustion process which will greatly accelerate corrosion (rust).

It’s an OK muffler I guess I bought to use on a generator didn’t quite it down much most noise I guess is coming from the engine and not the exhaust.

Was looking for the biggest muffler I could find with a 1.5" inlet to replace my rusted in half, rattling, factory exhaust. It's not super quiet but a hell of a lot better than the old one. I also added a $9 defuser at the end to quiet it slightly more. I saved $5 by purchasing from Amazon warehouse

The muffler is very high quality, well built and most of all , it quiets a 350 Honda 4 wheeler. The 4 trax has little room for a muffler like this but it worked very compact install. The air intake of the carb is louder than the exaust. Will get another when or if needed. Thanks Walker. Ron

Great choice for oem soundPrice is fantasticIt even flows better than my old muffler

Arrived in good shape,wrong size,but it looks like a great muffler,

I have experience walker mufflers before in our shop, but I hat that it doesn't show the specs for the inlet and outlet on Amazon, I had to purchase just to see and when it arrived, it doesn't fit my vehicle, had to send back, this one is more for an import rize burner. My application is a 96 c1500, I decided to go with dynomax ultra flo ss polished, at least I know what I'm looking at on the specs.
