You may need to add a seaplane lip to help with cooling so I would keep that in mind when it comes to the bottom cowling.

What are those rubber hoses on the exhaust supports? Are they joining two pieces acting like a flexible connector? If so,good.View attachment 41060View attachment 41061
Next is the Oil cooler Not sure if I want it on the Baffling or mounted to the Firewall with a duct from the baffling
Any suggestions pro's and con's

Exactly.
3/8 stainless tubing with 2.5" of hose. holds good and gives some dampening
im thinking the oil cooler will mount to the firewall with a support to the engine mount.
Still looking for ideas for this one.
Wouldn't solid support back to the engine be better? Those "dampers" will allow flex. With enough flex cycles something will crack and break. Wouldn't the exhaust and engine being tied together as one unit be preferred?
If the supports in the above picture were solid, it would be necessary for the clamps where they attach to the tail pipe to be a loose slip fit. If not, the stresses when the pipes heat up and are shaken will break the end of the support tube or some other component where it is attached. There needs to be a place for motion even if it is only the clamp being able to slide on the tailpipe.Wouldn't solid support back to the engine be better? Those "dampers" will allow flex.

Avnxtek, the cowl support rods that you have attached to the motor mount, where did you find the aluminum blocks mounted on the motor mount? They look much better than the piper clamp that most use. Good looking work, I also had to put a blister on my cowling to allow room for the Vetterman exhaust, my cowl is carbon fiber so a little easier to form. Thanks
Kind of hard to tell from the pictures but the vents look to me to be more pockets for the exhaust. The actual open vent area looks small compared to a reg lower cowling.

Is this for carb heat? If so, if you find that you need more heat you could close up that opening considerably.
Just fit your baffles tight enough to prevent as much airflow as possible to pass from the top to the underneath in this area, You want all of the cooling air to pass through the cylinder fins. Some make a streamlined shroud that fits behind the flywheel others just fit flat stock in tight. Same results. If you had a high speed airplane it may pay off to spend some time with streamlining the baffles.I have the Baffling around the flywheel to go yet. I see some use it and some don't any opinions on that?
where did you get the throttle levers, pretty cool.
This is where you make your own. Study your wings for every place that you may need access or that there is something that may need looking at. Then place an inspection ring there making sure that you have room to get your hand in and around any obstruction that may be there. Don't depend on someone else's drawing....So so ready to start on the wings
Anyone have a good drawing for inspection hole placement ?
