[QUOTE="DualSportr, post: 88787, member: 19592"] It always depends on how the sound test is done. And without a tach, there's absolutely no way to know if you're getting a correct reading or not. I did test a BBR piped TTR at our last Poker Run. It was below the 99 dB sound limit, tested at 3,425 rpm. I don't remember what the exact number was, so I'm not going to say, but I believe it ran in the 97 dB range. The only other TTR with an aftermarket system was one running the Big Gun. It tested at 95/96. Very close. [/QUOTE]
