Detailed Description

Built for front-position exhaust service, Bosal 287-703 uses a round aluminized steel resonator body with a 19.5-inch body length and flanged inlet and outlet connections. The direct-fit design supports OE-style replacement on 1999 Infiniti I30, 1996 Infiniti I30, 1999 Nissan Maxima, and 1995-1996 Nissan Maxima front silencer applications listed for vehicles without an oxygen sensor port. This part number is also identified as 287-703 for easy catalog matching.

Compatible With 1999 Infiniti I30, front; 1999 Nissan Maxima, front; 1996 Infiniti I30, front; and 1995-1996 Nissan Maxima, front. The Bosal 287-703 resonator is a practical choice when the goal is to restore a factory-like exhaust tone while maintaining a direct replacement layout. BRExhaust Direct-Fit Exhaust Resonator 287-703 is built around OE-style dimensions and connection points for these specific applications.

Common Issues It Can Address

• Excessive exhaust drone at cruising speeds
• Unwanted rasp or harsh exhaust tone
• Corrosion-related deterioration of the original resonator
• Backpressure changes caused by a damaged or restricted resonator
• Fitment problems from a worn or non-OE-style exhaust section

Installation Notes and Tips

Verify the vehicle’s front silencer configuration, oxygen sensor port requirement, and emissions notes before installation. This resonator uses flanged inlet and outlet connections with two bolt holes at each flange, so the mating exhaust surfaces should be inspected for alignment and sealing condition. Confirm the application details for 1999 Nissan Maxima split-date coverage and California emissions notes on the listed Infiniti I30 and Nissan Maxima vehicles.

Quality Assurance

Bosal designs the BRExhaust Direct-Fit Exhaust Resonator line to provide OE-style fitment, corrosion protection, and exhaust noise control for the specified applications. The aluminized steel construction supports durability in everyday exhaust service.
