Product Details

Walker SoundFX Direct Fit 18204 is built for drivers replacing a worn exhaust muffler on older Toyota trucks and SUVs, including 1979-1995 Toyota Pickup and 1985-1989 Toyota 4Runner applications listed below. The 19-inch body length and 23-inch overall length support a direct-fit installation on the specified exhaust layouts, while the offset inlet and outlet configuration matches the factory-style routing used on these vehicles. This part cross-references AP Exhaust 44841 and Gates 43046 for the same application.

Installation Notes and Tips

Confirm the vehicle emission system and exhaust layout before ordering, since some Toyota Pickup and Toyota 4Runner applications require part 35489 and/or optional split-system components. The fitment notes also specify two insulators for several applications, and OE insulators should not be reused. Verify inlet and outlet orientation, offset dimensions, and overall length against the existing exhaust before installation.

Quality Assurance

Walker SoundFX Direct Fit mufflers use 100% aluminized steel, mechanical interior joints, and spun-locked heads to support durability in exhaust service. The aluminized finish and direct-fit construction are intended to provide a consistent replacement for select Toyota Pickup and Toyota 4Runner exhaust systems.

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
