Thanks, friendly and responsive folks. Here is their reply for anyone else. I found it to be a bit pricey. I need the inserts, but I think I'll skip the $200 for the end caps.
Hi Mike,
It looks like the pipes that you purchased are the snorkel end cap type so what you see in terms of end cap is what you get. You can however replace the snorkel end caps with carbon fiber ones, you just need to buy the Carbon Fiber end caps and drill out and re-rivet them in place of the snorkel ones. Below is the pricing on everything you will need along with pricing on the quiet inserts.
