The muffler shield and bar-end weights are exclusive to the Executive however I did see some chrome aftermarket bar-end weights at a motorcycle shop. You may want to do a search on the internet to see if the bar-end weights can be purchased on-line. A chrome shop could take care of the muffler shield.
Alas, plastics can be plated. It's not an electro-plating process, but rather a vacuum-plating one. Do a google search for more info. I used to work for a furniture company that used vacuum plated plastic part as trim caps and connectors on some of it's products.
Even if Suzuki doesn't offer chrome bar-ends and muffler shields to the consummer as an after-market accessory, I'm sure once the supply line is filled they'll be available to dealers for repairing damaged Execs. If so, you should be able to order them -- eventually -- through any dealer.
