Type 25 Exhaust Bundle Kit - 1986-92 - 1700cc Diesel (KY Engines)

This exhaust silencer is a direct replacement for Volkswagen T3 / Type 25 buses fitted with the 1.7 diesel KY engine. The silencer is responsible for reducing exhaust noise while maintaining correct exhaust back pressure, helping the engine run smoothly, quietly, and efficiently.

Designed to original dimensions, this silencer restores factory-style sound levels without restricting exhaust flow. A worn or corroded silencer can lead to excessive noise, rattles, exhaust leaks, and failed MOTs. Replacing it ensures quieter operation, improved driving comfort, and proper exhaust system function.

Ideal for maintenance, repairs, or restorations, this unit fits directly in place of the original silencer on KY diesel models.

Key features

• Part type: Rear exhaust silencer / muffler

• Engine: 1.7 Diesel – KY

• Designed for correct noise suppression and exhaust flow

• Direct replacement for original unit

• 1.7 Diesel KY: 08/1984 – 07/1992

  • Bus

  • Van

  • Platform / Chassis

This front exhaust pipe is fitted before the exhaust silencer on Volkswagen Type 25 / T3 buses equipped with the 1700cc diesel KY engine. It forms the critical link between the engine exhaust outlet and the front muffler, carrying exhaust gases rearwards while maintaining correct alignment and flow through the system.

Manufactured to original specifications, this pipe ensures proper exhaust routing and correct positioning of the silencer. A worn or corroded front pipe can cause exhaust leaks, excessive noise, loss of performance, and MOT failures. Replacing it restores a gas-tight exhaust system and helps protect downstream components from vibration and stress.

This pipe is designed specifically for KY diesel engines, where exhaust layout differs from other T3 diesel variants.

Key details

• Part type: Front exhaust pipe

• Fitting position: Front (before the exhaust silencer)

• Exhaust system: For front muffler

• Engine code: KY – 1.7 Diesel

Related parts to consider
