Review on πŸ”‡ Walker Exhaust Quiet-Flow 21337 Muffler for Enhanced Engine Performance by Charles Butler

Revainrating 4 out of 5

No Drone Factory Replacement

I installed this on a 2012 Ford Fusion. They replaced the previous MagnaFlow muffler with more rumble. I chose an inlet/outlet of this diameter to continue the existing factory size tubing. In comparison, this can be less flow restrictive than Original Equipment factory mufflers which have a reduced outlet size. A solid price for an SS muffler without the hum of a performance muffler.

Pros
  • This is great
Cons
  • Repair
