Review on 🔇 Walker Exhaust Quiet-Flow 21539 Performance Exhaust Muffler by Robert Dabney

The stainless steel OEM replacement muffler is second to none. 1/3 the price the local body shop and muffler shop quoted for this part alone. Contrary to what the Walker website says, we did NOT have to purchase an intake pipe adapter, this muffler simply slipped over the factory pipe after the old muffler was cut off. The stock F150 exhaust was also reusable (made of inferior stainless steel) with just a small adaptor.
