Product Details

The BRExhaust Replacement Exhaust Insulator line focuses on OE-style exhaust support parts that mount correctly and hold the exhaust system in position. This rubber insulator is intended for rear silencer hanger locations on select Mercedes-Benz models, including the Mercedes-Benz E320 and 300TE, where a stable exhaust mount helps reduce movement and maintain alignment. If you are replacing a deteriorated exhaust hanger on a Mercedes-Benz 300SE or 560SEL, 255-079 provides a direct-fit replacement option built around the listed application data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Sagging or misaligned exhaust components
• Noise caused by a worn or cracked hanger insulator
• Excess exhaust movement at the rear silencer mount
• Stress on nearby exhaust joints and brackets
• Replacement needs for aging Mercedes-Benz exhaust support hardware

Installation Notes

Verify the rear silencer mounting location against the vehicle-specific fitment before installation. Inspect the surrounding hanger bracket, exhaust pipe alignment, and rubber condition so the replacement insulator seats properly. For Mercedes-Benz E320, 300TE, and other listed applications, confirm the side and position shown in the fitment notes before ordering.

Quality Assurance

Bosal manufactures this BRExhaust insulator from premium rubber for replacement use in exhaust support applications. The design is intended to match the listed fitment and help keep exhaust components positioned correctly for dependable service.
