4-21-13 Central IL SVT and Performance Fords Show MY DYNO

Well I got 2 runs with the dyno. One with the Silver key and the last with the Red key.
Posted are the 2 videos and the sheet.
As you can clearly see the red key had more hp and tq though the band, or more useable hp and tq when racing. Both ended up with about the same hp (379hp) but the torques with the silver key was 324.59 and the red key it was 339.49.
All in all I was happy with the numbers. But I wonder what the numbers would have been with the stock restrictive mufflers were still in. I had the less restrictive Roush axle backs, and when you factor in the .17% for parasitic loss it is right at 444 hp as advertised.

Here are the links.

Roush Review 4-9-13

After driving the Boss about four or five times I would like to report that the Sound is Awesome. A lot meaner. especially with the sides uncorked. truley sounds like a mean machine (retro).
I noticed quite a few people rolling there windows down and listening to the sweet exhaust sound.
Quality was excellent. Instructions on install could be better. (install Mids before reattaching Mufflers first . not other way around (rear end binds pipe so you cant get the movement needed to put mids back in unless mufflers are off.
Money well spent. Now if only the weather would be better so I could drive it more!!

3-24-13 INSTALLED ROUSH EXHAUST

WOW , very nice low rumble and an agressive tone compared to stock. I do notice a drone at 60-65mph but thats OK as I never drive that anyway haha.
Install was a snap but the instructions need an update. I found it easier to install the Mid pipes first then tails instead of the opposite that the instructions called for. Quality is excellent. there are even little drain holes in the bottom to allow moisture buildup to escape instead of sit inside the muffler.
Below are the comparisons Pics of Both old and new as well as Vids.
