Exhaust fitting kits contain all the clamps, rubber mounting bushes, distance tubes, insulation washers, and fixings needed for a complete exhaust system installation. Each kit is tailored to a specific system type and chassis number range, reflecting the mounting changes that occurred during production.
Exhaust Fitting
The fitting kit is just as important as the exhaust system itself. Perished rubber bushes allow the system to vibrate, creating stress at the joints that leads to cracking and premature failure. Corroded clamps may not grip properly, allowing joints to separate. Distance tubes and insulation washers prevent metal-to-metal contact between the system and its mounting points, which would otherwise transmit exhaust vibration and heat directly into the body structure.
Exhaust Fitting (Notes)
When fitting a new exhaust, all bolts and clamps should be left loose until the entire system is in position and correctly aligned relative to the bodywork. The system should then be tightened progressively from the manifold rearward, allowing each joint to settle naturally before being locked. Tightening from the rear forward forces the system into an unnatural position and places stress on the joints. Exhaust assembly paste applied to each joint during fitment provides a gas-tight seal and makes future disassembly considerably easier.
Fitting Kit Variants by Model
Fitting kits differ between the 1275cc and 1500cc exhaust systems, and within each range there are further variations by chassis number. The 1275cc kits cover three system types (Type 1, Type 2, and Type 3), each with different mounting arrangements. The 1500 kit changed at two chassis number breakpoints during production. The chassis number must be quoted when ordering to ensure the correct kit is supplied.
