This is just amazing! It is so much louder now. My Taurus sounds like a beast now! It was very easy to install I did it by myself in about 40 minutes. It was a pretty tight fit, but in the end you can tell it was made for my car. Haven't noticed much power increase or any better gas millage. But I have noticed it has made my car a little faster. Overall, I would recommend it to anyone wanting a nice performance piece in their car!
If you're reading this, buy it
I had one on my 2012 na Taurus. I got a 2013 sho and didn't like the fuel economy, so I got this. If I keep my foot out of it, I get 2-3 mpg more than stock. Sound is slightly louder. Performance may be better, but I didn't dyno it out anything. Install took 30 minutes.
