    has anyone tried the mid mounted flowmasters yet and if so how is and would you recommend it. what did you pay for the install. i got a qoute from a guy who said he could do it for 480. if anyone has any info on this that would be great.
  2. what gears to get on my 2008 Mustang gt/cs

    anyone know what the mpg's will be on the highway with 4:10s. i have been debating on if i should get these gears or not. And also what the rpm range is going to be at 65 and 70. my only problem is spending to much on gas right now. thanks
