I'm looking into getting an exhaust system but can't decide which one. What's the differences in these and which one will give me more MPH and HP? Sadly I get about 14mpg and have to pump gas every two days :/ any other way to save gas will be great help. Thanks
I'm guessing yours is a '10 if you don't have duals... Get an H pipe to make it deeper, and look around youtube for a set of mufflers you like. Remember, the 4.0 is probably the worst sounding engine in the Mustangs, so you don't want it too loud and raspy.
