Type 25 Exhaust Bundle Kit - 1986-92 1900cc Waterboxer (DG Engines)

This replacement exhaust muffler (silencer) is designed for non-catalytic Volkswagen VW Type 25 / T3 buses built from 1986 to 1992 and fitted with 1.9 or 2.1 Waterboxer petrol engines. It is a direct-fit solution for vehicles WITHOUT a catalytic converter, restoring factory-style exhaust noise levels and correct gas flow.

The silencer’s internal baffle and chamber design absorbs and redirects sound waves produced by the engine, significantly reducing exhaust noise while preserving the back pressure these engines require for smooth running and reliable torque delivery. Correct exhaust flow is essential on Waterboxer engines to maintain drivability, throttle response, and engine longevity—this unit is engineered to deliver that balance.

Manufactured from durable, corrosion-resistant materials, this muffler is built to withstand heat cycles, moisture, and everyday road use. Its robust construction helps prevent premature failure from rust or cracking, making it ideal for regular drivers, restorations, or MOT-related repairs. Fitment is straightforward, aligning with the original exhaust pipework on non-cat systems with no modifications required.

This exhaust fitting kit is a complete hardware solution for refitting or replacing the exhaust system on Volkswagen Type 25 / T3 models fitted with 1.9 and 2.1 Waterboxer engines. It contains all the essential gaskets, nuts and bolts required to correctly mount the exhaust manifolds, silencer and tailpipe, ensuring a secure, gas-tight installation.

Over time, exhaust fasteners are exposed to extreme heat cycles, moisture and road grime, which causes corrosion, seized fixings and exhaust leaks. When fitting a new exhaust, reusing old hardware often leads to poor sealing, snapped studs or premature failure. This kit eliminates those issues by providing all the correct components in one package, matched to Waterboxer exhaust layouts.

The gaskets ensure a proper seal between exhaust joints, preventing leaks that can reduce engine efficiency, increase noise, and allow fumes to escape. The supplied nuts and bolts are sized specifically for the original exhaust system, allowing correct clamping force and alignment across the full system, including the tailpipe connection.

How it works

Each gasket is designed to compress evenly between mating exhaust surfaces, compensating for heat expansion and vibration. The correct-grade fixings maintain tension under high temperatures, keeping the exhaust securely mounted and aligned with the engine and body. This results in quieter operation, improved exhaust flow and long-term reliability.
