not to long ago i got a 04 f150 and it has a 3 year powertrain warranty which means im limited to what i can do with the truck. The sales guy did say that i can put an exhaust on the truck but it cant cause any harm to the motor because it will throw the warranty out the window does anyone have any tips for me because i need a exhaust system

 

a Flowmaster or Magnaflow exhaust kit you will be safe with if you dont want to go custom and risk voiding your warranty

 

as long as you leave the Y pipe forward alone, you pretty much have any freedom to do what you'd like

 

thanks alot now i get to put the exhaust that i want to do

 

but thats all i have to do just leave the stock y pipe

 

yah Y pipe forward, like the cross over, cats and headers are off limits....
