2011-2013 Mustang V6 Roush Exhaust Sound Clips & Review

The Roush axle-back exhaust system for the 3.7L 2011 Mustang V6 is in a class of it’s own. They’re some of the most affordable mufflers and add some of the most noticable differences than many other after-market axle-back exhausts. It’s agressive exhaust note makes the V6 Mustang sound what is was born to be, a true American muscle car.

The exhaust note dampened a bit after about 100 miles but it was so insignificant only the driver will notice. At idle it completely transforms the sound to that of a V8; nice and deep, loud, and bassy as well as below 2000 rpm. When the revs climb above 3000 rpm the Roushs absolutely scream and become a bit raspy while keeping a bit of a low tone in the background and then slightly deepen again around 6000 rpm. They’re quiet while coasting so one would without a doubt want to coast by any cops.

There is a significant amount of drone but definitely not the worst in the after-market exhaust market. The drone is obviously the worst at 2000 rpm and is managable around 1700 rpm. Overall it’s not really a big problem to hold a conversation with a passenger or while listening to the radio.

The mufflers and tips look great on the Stang. The large 4″ polished tips outshine the cheap stock tips on so many levels and the smaller mufflers (“cans”) are almost unoticable making for a much cleaner look. The entire look of the back end is improved because of these mufflers (or any other similar looking mufflers for that matter). Installation shouldn’t be too hard, it’s essentially loossening the stock mufflers and removing them from the hanging rubber brackets and then doing the reverse with the Roush axle-backs. However, if you can’t find a way to lift the car off the ground (or at least the rear wheels) you’ll have to take it into a shop to have them installed which can typically cost up to $100.

A major thing to note: the noise level (while obviously loud throughout the spectrum) is determined by how hard the throttle is punched. The harder the throttle goes down the louder (and higher pitched) the exhaust is. Overall these Roush axle-back exhausts are much, much louder than stock and it isn’t difficult to see why so many people end up returning them or reselling them because they think they are too loud and obnoxious. Lastly, absolutely coast by any cops. With these monsters on you’ll be attracting everyone’s attention while you accelerate only to make yourself a target… people aren’t lying when they say these things are a major head turner.

Loudness (volume): 4.5/5
Exhaust Note: 4.5/5
Fit & Finish: 5/5
Bang for your Buck: 5/5
Installation time: About 1 hour

Do you think you’ll be getting the Roush axle-backs? If not, why and which ones will you get instead?

Get FireFox 3.7a3 Now!

FireFox has become more and more popular over the years and there’s no doubt in my mind that it will one day overtake Internet Explorer to become the most popular web browser. Although there is such a great number of people who use Mozilla’s prized browser, not many of them know that Mozilla has released alpha (pre-beta) versions of FireFox 3.7.

Before I moved from FireFox 3.6 to FireFox 3.7 alpha3, 3.6 was constantly using roughly 80%-95% of my MacBook Pro’s CPU. Even at idle it would use more memory than it should have. Because of this it slowed everything down and I was never able to find out why this had occurred. So I started searching for a later beta version of FireFox just to see if anything had been released yet. Well, FireFox 3.7alpha3 was released. So I downloaded the alpha version and started to run some tests. This new version, even in it’s alpha stages, is faster than 3.6, takes up less CPU space (about 30%-65% when loading, about 3% on idle).

As with all pre-GA (general ability) software, there is bound to some bugs, I guarantee it. Also, so far no add-ons are available for it, however, as it moves up in development stages, compatible add-ons will be released (most likely once it’s in beta stages). If you’d like to get Mozilla FireFox 3.7a3 to try out on your own, click HERE. To download the web browser is a little tricky because you have to sort your way through Mozilla’s FTP server.
