We add ball joints on 2 of the 4 cylinders and 2 of the 6 cylinder. This allows a couple of the cylinders to “free float” and not cause stress on other primaries or on the collector. Most of the time the collector has the tailpipe attached and is the end of the system. In most cases the collector is out on an “arm” which if not supported properly could lead to premature failure. All kits come with a clamp with a mount so the end of the system can be properly supported. The collector style exhaust has a preset price, and includes one cabin or carb heat shroud, tailpipe support clamps and brackets, collector mounting hardware and links. In some cases there are complex systems, at that time the price will not be set. We will inform you immediately in this situation. If you wish to have a second shroud for cabin or carb, there will be an additional cost.
AE builds the cabin and carb heat shrouds from stainless steel to assure that there will be no failures due to the extreme heat from the primary in which it is wrapped around.
Carb heat muff can also be supplied on carburetor engines, this is not included in the standard price. It also mounts on a primary tube but only requires 4-6” of straight. The carb heat has a series of holes which draw air from the engine area into the muff as it is pulled past the primary it is heated and is sucked into the carb creating carb heat of 95+ degrees over ambient – (FAA requirement for temp rise for carb heat on certified aircraft). Both the cabin and carb heat shrouds are 3” OD with a port in and a port out. Typical scat size for good air flow is 2”.
The collector is held on to the primaries with a heavy duty link that crosses over the slip joints and bolts into the welded brackets that are on the two primaries and two slips on the collector. This is done for many reasons, the installation requires this type of system and it is also done for inspections and shipping breakdown.
