Flowmater Mufflers?

OK.....Last July, I took my junk out to the middle of nowhere to a dyno shop that RJF suggested.... here are a couple clips of the "hard pulls" they did. Each vehicle went over 100MPH on the dyno......
Hearing Swampers at 100+ is scary! Everyone in the shop took a few steps back from the machine as it was making it's pull.
1st one:
'72K5 - 396BBC/Thorley TriY Headers/ Flowmaster 70-series duals / 4.10s & 38's....you can see the "Detroit Locker effect" when the throttle lifts too! (6MB)
http://www.norcalbigdawgs.net/bb03/pics/Dyno%20Day%20-%20K5%20Hard%20Pull.MPG
and this (bonus footage!)....
'72 Burb - 350SBC with cast manifolds and Walker Dynomax duals (12MB)
http://www.norcalbigdawgs.net/bb03/pics/Dyno%20Day%20-%20Suburban%20Hard%20Pull.MPG
Final results (I still can't find the dyno sheets, but there here somewhere) were that the K5 put down just over 300 Lb/ft of torque at the wheels, and the Burb (even with a smallblock!) put down 292!!! Talk about embarassing for the BBC!!!.....
Enjoy!

just saw the thread on exhaust and thought what a coincidence iI was looking at exhaust for 72 k5 today and looking for that same sound - quiet down the road but when stomped on I want it to sound like I got some horses under the hood! I'm looking at going with Flotech headers and magnaflow exhaust. Does anybody have feedback on the Flotech headers?
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&tc=photo&item=7947544073&category=33636I put true dual exaust on my wifes 89. 2 catco converters and 2 40 flowmasters. I love the sound. I am getting 2 more for my big truck.
