Terrafirma centre silencer replacement pipe – Defender 90 300Tdi TF551

Centre silencer replacement pipe

TF551 replaces the centre silencer on Defender 90 with the 300Tdi engine, model years 1994–1997. It is a replacement pipe rather than a silencer, and changes the exhaust sound.

• Vehicle: Defender 90.
• Engine: 300Tdi.
• Years: 1994–1997.
• Material: 1.5 mm grade 409 stainless steel.

Terrafirma describes grade 409 as a ferritic stainless steel used in exhaust systems for its formability, weldability and resistance to atmospheric and exhaust-gas corrosion. Light surface rust can form; the material is not intended to retain a decorative polished finish.

For vehicles from 1997, check the existing pipe and connections before ordering: the supplier lists 1994–1997, while the original catalogue description specifies pre-1997.
