Description

Quiet your exhaust and hush drone with the Walker SoundFX Direct Fit Exhaust Muffler 18577 — a WALKER EXHAUST muffler that drops in as a direct-fit, bolt-on replacement for the 1997-2004 Ford Pickup F100 and the 1997-1999 Ford Pickup F250 Series 3/4 Ton. It carries a 2.5" inlet (ID) and 2.5" outlet (ID) and installs with factory-style routings, brackets and hangers, so no specialized fabrication or welding is required.

Aluminized steel construction: built with 100% aluminized steel plus an internal drainage system to help reduce corrosion for longer service life versus low-carbon steel.
Built for stability: 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 add durability.
Factory-style sound: louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes.

Designed and tested to extend muffler life, this SoundFX muffler delivers quality appearance and favorable acoustics. See the Buyer's Guide tab for engine-level fitment details.
