- 100% aluminized steel construction for improved corrosion resistance
- Offset inlet and offset outlet with 2-bolt welded flange connections

Detailed Description
Walker 18908 is built for drivers replacing a worn exhaust muffler on 1998-2004 Isuzu Rodeo without Sport Package, 2002-2003 Isuzu Axiom, and 1998-2002 Honda Passport models. The direct-fit configuration supports a straightforward replacement on the listed vehicles, with a 2-bolt welded flange inlet and outlet, offset inlet and outlet placement, and an overall length of 36.5 in. The aluminized steel body helps resist rust better than low-carbon steel, while the SoundFX Direct Fit line is aimed at maintaining factory-style exhaust tone and appearance. This part cross-references AP Exhaust 700426 for the same application.
What It Helps Address
- Exhaust noise from a rusted or internally damaged muffler
- Corrosion-related muffler failure on older factory exhaust systems
- Restricted exhaust flow caused by a deteriorated muffler core
- Fitment issues when replacing an original muffler with the wrong configuration
- Loss of OE-style exhaust appearance on Isuzu Rodeo, Isuzu Axiom, and Honda Passport models
Installation Notes and Tips
Verify flange style, inlet and outlet offset, and body dimensions before installation. This muffler is not reversible and is not tunable, so it should be matched to the listed exhaust routing and vehicle application. Confirm compatibility with your exact year and model before ordering, especially for 1998-2004 Isuzu Rodeo without Sport Package, 2002-2003 Isuzu Axiom, and 1998-2002 Honda Passport.
