Review on 🔇 Walker Exhaust Quiet-Flow 21539 Performance Exhaust Muffler by Moises Dzihic

Good muffler that does what it says - it's quiet compared to most mufflers and way better than my blown model! The shop had to make some minor modifications to fit my 04 F150, which an "expert" from the muffler shop told me had the original muffler, but I doubt that as my truck has over 200,000 miles on it and I only bought it a month ago so I don't know what has been done to it in the past. According to Walker, it should be a straight muffler, but I had to make small adjustments to make it work. I would recommend this muffler to anyone who needs a quiet muffler for a full size truck.
