flowmaster

I recently had a single inlet dual outlet flowsound muffler installed. Here is the clips. Let me know what you think!!

Just got my '06 RT a few weeks ago. The previous owner replaced the original muffler with Flowmaster, suggesting that it would help improve fuel efficiency for the truck. Has anyone done this and seen improvements in MPG? Are there potential problems with using the Flowmaster? Just curious how...

so i came across dynomax super turbo muffler.... and this video of a wrnagler with the same exhaust... am i wrong to compare the sound of the ridgeline to the sound of a wrangler... exhaust ..... http://www.dynomax.com/mufflers.php?muffler=superturbo wrangler sound.... also wanted to know...
