700 Exhaust tips?

I am going with the EHS fuel controller and a exhaust tip.

What’s the difference between the R2 racing tip and the EHS tip? They look the same?

Being many complain about the loudness of the R2 tip is there any company producing a quieter tip?

I found a nice stainless steel one with a 90 downturn (armortech #259181 can’t find anyone who sells it !

Just want to buy the right tip the first time.

Thanks for any help.
