2014 5.0 GT power and exhaust questions
 

Hey guys I have a 2014 stock GT with Flowmaster outlaw axle-backs on it and just have a few questions about power gain and exhausts!


1.) Do I lose and power or gas mileage with my Flowmaster outlaw axle-back deletes?


2.) Can you put aftermarket headers on with the stock exhaust system?
How much power would you gain and what would it sound like?


3.) What are the first top 3 things to do to get the most naturally aspirated power out of the engine?
