FWF Kit Exhaust and Baffling

Apparently there is an 8 week back log at Vans for the exhaust and baffling parts of the FWF kit. Anyone know of other vendors that might provide like products for the stock IO-390 RV-14A design?

It is possible to make your own baffles from scratch. I did this a couple of times in the dark ages of building. Mate paper templates an transfer those to aluminum. Van?s may have some old baffle plans on file.
