Detailed Description

Built for select Ford E-Series vans, AP Exhaust 700440 is an aluminized steel exhaust muffler with an oval body and baffled internal construction. The 3-inch pipe inlet and outlet, along with the right-center inlet and left-center outlet locations, match the factory-style exhaust path used on covered applications. This makes it a practical replacement for vehicles that originally used a welded OE muffler assembly.

Compatible With 1997-2002 Ford E-150 Econoline, 1997-2002 Ford E-150 Econoline Club Wagon, 1997-2002 Ford E-250 Econoline, 1997-2002 Ford E-350 Econoline Club Wagon, 1997-1998 Ford E-350 Econoline, and 2003 Ford E-150, E-250, and E-350 Club Wagon applications. AP Exhaust 700440 is also listed for 2003 Ford E-150 and E-250 vans, plus California and non-California E-350 Club Wagon configurations shown in the fitment data.

Common Uses

• Replacing a rusted or damaged factory muffler on Ford E-Series vans
• Restoring exhaust flow after failure in a welded OE muffler assembly
• Addressing exhaust noise that has become louder than factory levels
• Replacing a muffler with incorrect inlet and outlet centerline locations
• Servicing 3-inch exhaust systems on covered E-150, E-250, and E-350 applications

Installation Notes and Tips

Verify the inlet and outlet locations, pipe diameter, and overall length against the existing exhaust before installation. Because the OE system was a welded assembly on the listed applications, replacement often requires matching the full exhaust section noted in the vehicle-specific fitment comments. Confirm whether the vehicle is a California model where noted in the fitment data, especially for 2003 Ford E-350 Club Wagon and earlier E-350 Econoline applications.

Quality Assurance

AP Exhaust manufactures this muffler in aluminized steel for regular-duty exhaust service. The MSL series uses a baffled design and OE-comparable sound level to support factory-style replacement on the specified Ford E-Series vans.
