RS*R ex-mag exhaust

I know there are a crap load of "what exhaust should I get" threads but seeing as I have a specific question I didn't just want to tag it on to the end of one of those.

A while back (few weeks maybe) there was a thread about dB numbers for different exhaust systems. I don't remember who had the numbers but whoever it was hadn't gotten a dB value for the Ex-mag and was still trying to get one

I was wondering if anyone has seen any numbers for this exhaust, and or has heard it and can directly compare it to the thermal stealth system

thanks
