Detailed Description

Bosal BRExhaust 255-631 is an exhaust system hanger insulator made for replacement use on select Nissan 300ZX, Pulsar, Pulsar NX, Sentra, and X-Trail models. This exhaust hanger insulator is used to secure exhaust components in the proper position, helping reduce movement at the front pipe and rear silencer mounting points. The BRExhaust Replacement Exhaust Insulator line focuses on OE-style fitment for car, truck, and van exhaust service, and this part follows that approach for the listed Nissan applications.

Compatible With 1983-1989 Nissan 300ZX, front pipe and rear silencer; 1983-1986 Nissan Pulsar and Pulsar NX, front pipe and rear silencer positions; 1983-1985 Nissan Sentra, front pipe and rear silencer positions; and 2005-2006 Nissan X-Trail, rear silencer. The Bosal 255-631 is a practical replacement when the original hanger insulator is worn, cracked, or no longer holding the exhaust in place.

What It Helps Address

• Broken or cracked exhaust hanger rubber
• Exhaust movement at the front pipe or rear silencer
• Noise from a loose exhaust mounting point
• Misalignment of exhaust components after hanger wear
• Premature stress on exhaust system joints and mounts

Installation Notes and Tips

Verify the vehicle year, model, and exhaust position before ordering. This part is listed for rear silencer and front pipe applications depending on the vehicle, so match the original hanger location to the fitment notes. Inspect adjacent exhaust hangers and mounting points during replacement to confirm the rest of the system is secure.

Quality Assurance

BRExhaust replacement insulator mounts are manufactured from premium rubber and built as OE-style replacements for the listed applications. This design supports proper exhaust positioning and consistent mounting performance on compatible Nissan vehicles.
