Got a quick question for the 14 builders. Saw a pic in Kitplanes (below) and the second heat muff caught my eye. Are the exhaust pipes 2”, and is the second heat muff listed as “heat muff aft” on the vans site?

May give it a try on my -7, but don’t want do drop money on a part that won’t work.

Different muff...

I have Van’s stock four-into-one exhaust and muffs on my -14. The aft muff is not stubby like that one, so I don’t know what muff you’re looking at in that picture.

I think that is the 390-EXP and they went back to a two pipe exit on that 14 vs the 4 into 1

Yes, the second heat muff pictured was on the new engine option for the -14. Maybe the FWF for that engine hasn’t officially been released yet.

Interested in the PN. May try incorporating it on my -7.

Looking at that picture I'm curious about the center tunnel cover with the cowl flap.
