so i was readinn a post someon ehad the otehr day and someone was telling them to take off the rear cats to make the exhaust sound better.....i didnt know we had more than one set.....all v6 mustangs have more than one?....and if so what difference will i tmake if i take mine off....and will i still have to get mil eliminators or a tuner to get the check engine light off...

 

Yes you will need to get the mils or tuner to fool the computer. Our stangs have 4 cats but you can take the rear two off and it will sound deeper. Why not go with hi flows?
