so on a 2014 GT how much HP and torque could you expect to gain with long tube headers, off road H mid pipes and borla stingers cat back with a Tune? all pieces are Borla. i imagine it would sound awesome but is it worth the $3,000 price tag?
Full exhaust and tuner are the two most beneficial bolt ons you can buy. Your car will sound awesome but realistically you probably won't see but about 50hp with those. The stock setup isnt as restrictive as the older cars are.
