Product Details

The Bosal BRExhaust Replacement Exhaust Insulator line focuses on direct-fit exhaust hanger replacements that match original mounting points. Part number 255-623 is engineered for a range of Nissan and INFINITI exhaust locations, including rear silencer front and rear mounts, front silencer mounts, central silencer mounts, and front pipe support points. This makes it a practical choice for restoring proper exhaust positioning on vehicles such as the Nissan Frontier, Xterra, Sentra, and Maxima, as well as INFINITI G20 and I30 applications.

By replacing a deteriorated hanger insulator with a direct-fit rubber mount, the exhaust system stays supported in the correct location, which helps reduce movement at the mounting point and supports longer exhaust system service life. This part number 255-623 is listed across model years from 1986 through 2004, depending on vehicle and exhaust configuration.

What It Helps Fix

• Sagging or misaligned exhaust components
• Broken, cracked, or hardened hanger rubber
• Exhaust movement at silencer or pipe mounting points
• Noise caused by worn exhaust support insulators
• Premature wear at exhaust hangers and adjacent components

Installation Notes

Verify the exact year, make, model, emissions package, and exhaust location before ordering. Fitment varies by position and notes such as front silencer, rear silencer, central silencer, front pipe, federal emissions, California emissions, short box, and split-date applications. For example, it fits 2001-2004 Nissan Frontier, rear silencer front left or front right; 2002-2004 Nissan Xterra, rear silencer front left or front right; and 1999-2002 INFINITI G20, front silencer. Confirm the mounting point on the vehicle before installation.

Fits 2000-2001 Nissan Sentra, front silencer, federal emissions equipped; fits 1989-1994 Nissan Maxima, rear silencer front, center, or rear depending on application; and fits 1995-1998 Nissan 200SX, front silencer on listed emissions configurations. Part number 255-623 should be matched to the exact exhaust hanger location shown in the fitment data.
