I'm thinking about sneaking down to Hastings Thursday July 7th for their open track day 10-3 if you're ready to put it on the track 
. Haven't run it by the wife yet though

Yeah the roush mufflers in the box w/ all the packing material was pretty easy to pick up and move around, 25-30lbs total sounds about right.

Check out the 2011 GT500 mufflers sold through Ford Racing. Good price, good sound, lower backpressure and no drone/boom (factory tuned!). I'm pretty sure they run under $350/pair. If you've heard a GT500, then you can guess how they'll sound on a 5.0L...

Thinking of doing this. Any idea on the weight?
Mine just came in today. The Corsas weigh in at 12 lbs each. That will cut 30 lbs based on boss man's scale on the stockers.

Drove to Omaha today (110miles round trip), 55-68 mph the corsas have the dreaded drone, above 68mph starts decreasing drastically, between 73-85mph very light drone that is easy to talk without raising voice, I used a digital readout app on smart-phone to get the speeds I think the speedo on the Boss sucks, very hard to tell what speed you are going IMO. This was in 6th gear.
The corsas sound great inside the car, especially at WOT, I don't hear the side pipes any more, tomorrow I'll get a listen outside the car.

Glad to hear you like the sound of the Corsas. I'll know on mine this afternoon. Interesting that you don't hear the side pipes. That must mean freeing up the flow through the axle backs is working.
