I am looking for an eahaust for my 5.4 f-150 and i want the loudest exaust made, I want one that has that loud crackling sound to it.I wanna be heard!!

 

The loudest would be open headers - very doubtful that it's legal. Definitely hard on the engine!

True duals with straight pipes? - check your local laws.

If that's no good, then try adding a couple of short glasspacks.

Still not legal? Try the Gibson Supertruck- it's pretty loud.

 

FLOWMASTER 40 SERIES

------------------
98 Nascar Edition, Superchip, Airaid, Flowmaster 70 series, bedliner, in bed tool box, Profile bug deflector and window vents, Class III receiver hitch.

 

Flowmaster 40 series, the loudest they come legally. Also the bigger the tip the more amplified the exhaust.

------------------
2000 150 sport solid white, K&N filterpack the rest is still stock....for now anyway!
