Walker 21381 Quiet Flow Stainless Muffler Review

This muffler is a must-have for any automotive enthusiast. When I tried this product I was blown away by how quiet and smooth my car sounded .The muffler is made of stainless steel and won`t rust like other cheaper options. The only con I can think of is the price, but you definitely get what you pay for with the Quiet Flow muffler. Overall, I highly recommend this product for anyone looking for a high-quality exhaust upgrade..

As a result of my tests, I determined that this muffler may be "quiet" but it severely restricts air flow, compromising engine performance .The stainless steel construction is a plus but it doesnt make up for the lack of power in my vehicle..

The car's original exhaust lasted about 12 years before it had to be replaced. In northeast weather. Replaced everything from the engine but in less than 2 years it rusted again! The Y-pipe from the Wanderers rusted and broke off, then upon replacing I noticed there was rust on 2 mufflers and both thru. Walker had the mufflers replaced under warranty, but had to jump through tires. They ended up covering most of the cost of the new Y-tube as well, but Walker doesn't usually guarantee that part.
