I have the Fabspeed and SSIs on a modified 3.4 '83 911SC. the Fab is loud enough that I have to put 90-degree elbows on the tailpipes to direct the sound away from the noisemeters at Lime Rock, if they're in operation. Quality is superb. Have no butt-dyno answers for you, though, since I never drove the car before doing all the modifications.
