Default Vent block off FF-0084 and vetterman exhaust

With the vetterman exhaust, is the vent block off plate on the right side necessary? With one heat muff, I see that it probably should be, but does the vetterman come with 2 heat muffs, each feeding it's own side?

Thanks

Default Yes it does

Yes, two heat muffs. I added a second flange on the back left baffle with a second scat tube so each heat vent has its own source.

This shows the flange...





I considered that sourcing air from the aft baffle could introduce ?bad air? into the cabin but I haven?t noticed a difference between the right heat vent and the left except it may be a bit hotter.

I also didn?t use the stock heat valves but used stainless valves.

Great. Where did you source that flange?

Thanks

Default Flange Source

I sourced the flange from Aircraft Spruce:

Hi Jeff,

Where did you get the stainless heat valves? Are they completely stainless including the valve flapper? My MDR is requiring the flap to be stainless.

Default Also Spruce

I sourced the valves from plane innovations but I think they went away, I can?t find them on the internet anymore. Spruce has them though. Search:

HEATER BYPASS VALVE WITH CABIN SIDE CONTROL LEVER FOR RV-7, RV-8 AND RV-9

They will work on the -14.
