Product Details

The BRExhaust Direct-Fit Exhaust Resonator line is focused on application-specific exhaust replacement parts that install cleanly and preserve the original exhaust character. Part number 290-099 is a premium resonator assembly for the front position on 2009-2012 Nissan Altima vehicles, including 2010-2012 Nissan Altima front applications between the underbody converter and rear silencers, as well as 2010-2012 Nissan Altima front applications between the rear converter and rear silencers. For 2009 Nissan Altima, it fits the front silencer location between the underbody converter and rear silencers from 1/1/2009 onward.

This part cross-references Nissan 20300-ZN50A for the same application.

What It Helps Address

• Exhaust drone or resonance at the front silencer section
• Excessive exhaust noise compared with factory sound levels
• Corrosion-related replacement needs in the exhaust system
• Backpressure concerns caused by a worn or damaged resonator
• Fitment issues when replacing the original front resonator on a Nissan Altima

Installation Notes

Verify the vehicle year, engine/exhaust routing, and front-position configuration before installation. This resonator uses a flanged inlet and sleeved outlet, so the existing exhaust layout must match the listed application. Confirm whether the vehicle is equipped with the underbody converter or rear converter routing shown in the fitment notes for your Nissan Altima.

Quality Assurance

Bosal BRExhaust direct-fit exhaust components are engineered for application-specific replacement and built with aluminized steel to help resist corrosion in everyday driving conditions. Part number 290-099 is designed to restore factory-style exhaust performance and sound on the listed Nissan Altima applications.
