Maybe I'm just going deaf (OK, the years of loud rock and roll have probably caught up with me) and the 3" Pypes exhaust may have something to do with it, but I don't think my Mallory 140 is that loud (I don't know how it compares to the Summit pump). I've got 2 rubber pads to isolate the pump. One located between the mounting bracket and the trunk pan and another one between the pump and the mounting bracket. I seriously don't hear the pump running when I'm just cruising along with the car running at low RPMs, so I have no complaints.
It's hard to see, but here's a pic of how it's mounted: http://home.comcast.net/~gs470/LeManz283.jpg
