- 100% aluminized steel construction for improved corrosion resistance
- Mechanical interior joints and spun-locked heads for added durability

Product Details
Walker Part Number 18305 is built for direct replacement use on 1980-1987 Toyota Corolla and 1983-1988 Toyota Tercel without California Emission System. The SoundFX Direct Fit product line is engineered for application-specific installation, with dimensions that match the listed vehicle exhaust layout: 26-inch overall length, 17-inch body length, 7.75-inch body width, and 3.25-inch body height. The aluminized steel body and welded-style internal construction help the muffler hold up in everyday driving while preserving a factory-like exhaust note. This part cross-references BRExhaust 287-559 for the same application.
What This Muffler Helps Address
- Rust-through or corrosion in the original muffler
- Excessive exhaust noise from a worn internal baffle structure
- Exhaust leaks caused by deteriorated muffler housing
- Poor fit from universal muffler replacements
- Need for a direct-fit exhaust repair on Toyota Corolla or Toyota Tercel
Installation Notes and Tips
Compatible With 1980-1987 Toyota Corolla and 1983-1988 Toyota Tercel, this muffler uses a 1.75-inch pipe connection inlet with an offset inlet configuration and a center outlet tip. Verify exhaust pipe diameter, hanger alignment, and vehicle emission configuration before installation. Because this is a specific-fit muffler, it is intended to match the listed application rather than a universal exhaust setup. Part Number 18305 should be compared against the existing muffler dimensions and outlet routing before final assembly.
Quality Assurance
Walker SoundFX mufflers use aluminized steel, mechanical interior joints, and spun-locked heads to support durability and consistent fitment. The product line is built around direct-fit replacement standards for Toyota Corolla and Toyota Tercel exhaust service.
