Description of Walker 21507 Quiet Flow Stainless Muffler

CORROSION RESISTANT STAINLESS STEEL -- The only broad-market muffler with 100% stainless-steel construction that delivers longer life versus aluminized mufflers while an internal drainage system reduces moisture collection. EASY TO INSTALL -- Direct-fit bolt-on replacement solution with OE-style hangers, brackets and pipe routings for easy installation and doesn't require specialized fabrication and/or welding. BUILT TO LAST -- Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide stability and longer service life. PREMIUM ACOUSTIC CONTROL -- OE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for premium factory-style sound quality compared to straight perforated tubes. DESIGN VALIDATED -- Acoustic and flow tested for quality OE-style sound you can count on.

A Hushed Upgrade: my feedback

This muffler is simply amazing! Automotive buffs might know how frustrating it is to find a muffler that doesn't affect performance and is also quiet without being too soft. Through trial and error, I found that this particular muffler ended my search with its fantastic performance - crisp engine sound without the annoyance of loud exhaust notes.

Pros
  • The muffler performs perfectly, with the engine sounding crisp without being too loud.
Cons
  • None to speak of.

Wrong "just fit " size

Intake and exhaust were much smaller than 2003 f250 7.3. This results in a loss of performance due to clipping and is a problem in filling the gap.

Pros
  • Exhaust and Emissions
Cons
  • Some errors

Intake and exhaust pipes were much smaller than the factory f250 2003 7.3. This results in a loss of performance due to clipping and is a problem in filling the gap.

Pros
  • Replacement parts
Cons
  • Plenty
