The exhaust system on the Libra utilises the standard Rover Metro manifold After the manifold the exhaust system is all purpose designed in stainless steel. The exhaust system mounts directly to the engine gearbox assembly and not any other framework, on the car. The exhaust system as a small flexible section to take out the stresses generated by the expansion of the stainless steel. The exhaust system is so designed to allow the standard K Series Rover Metro catalyst to be fitted should the customer wish or this can be replaced by a special pipe of the same dimension as the catalyst. The silencer itself is straight through and as a stainless steel heat shield around it to prevent the boot on the Libra becoming warm.

Assembly

Mount the main exhaust silencer to the engine first with the engine mounted in the car, it is possible to manoeuvre the exhaust system through and below the main cross tube of the engine frame with care. On the driver’s side of the car mount the exhaust system mounting brackets to the two 10mm tapped holes just to the right looking from the rear of the dipstick. It may be necessary to slightly bend the dipstick out of the way of the exhaust bracket. The exhaust is attached to the engine using two 10mm socket cap head screws 15mm long and 10mm washers.

Fix the gearbox-mounting bracket to the driver's side of the exhaust system using the three 8mm diameter 10mm long set bolts and washers. By holding the exhaust system horizontal and square to the car it should be clear which two gearbox bolts have to be removed to bolt the exhaust system to the gearbox on the passenger side of the car. The exhaust system can now be bolted up firmly on both passenger and drivers side of the car and should be horizontal and true to the car.

Mount the stainless steel pipe with the flexible portion in it to the standard K Series Rover Metro manifold using the gasket provided and some exhaust paste.

The standard K Series Rover Metro catalyst can now be fitted between the two stainless steel plates of the exhaust system or the stainless steel pipe provided in the kit. Use one of the gaskets provided on either side of the stainless steel plate at both ends and attach at the driver's side using 10mm 13mm long set bolts, nuts and washers and paste. Now attach the 'U' section stainless steel between the end of the catalyst pipe and the silencer itself using gaskets and cement.

The new pipe attaches to the silencer using the same 10mm 30mm long set bolts. Tighten all bolts securely and when the engine is running check for any leaks.
