Has anyone used these guys?

Beautiful pipes, not much of a gain for performance, but sounds great...

Yes
Have one for a long period.
Very loud after 3400 rpm
You can’t hear original music anymore.
But extremely good engine response, no vibrations, no hesitation at all.
Top engine speed raise +500 rpm/

I tend to go in another direction when I read stuff like this on a someones write-up on their own product.

"Stealth technology being introduced to allow you both power and quiet performance."

I was wondering if you were alleging that one of the other posters was the producer of the exhaust, THEN I saw it was RSR. IIRC, they are among the kings of vaporware products (namely their LT clutch) and have all kinds of drivel on their site, including the #@$% You page directed at their disparagers. Am I confusing them with someone else?

I don't know much about those guys but their comments on the larger fuel injectors seem suspicious. Without a program map change, bigger injectors will do nothing. So I'm suspicious of their stuff, but I have no experience with them to go on.
