hey guys i have a 1975 ford f-250 with a 390 in it and i would like to make it sound a little bit more aggresive when i put my foot in it but not to aggresive, my truck is all stock and i would like to keep the idle fairly quite i olny have about $120 to spend on it so i cant get headers or anything i would just like to know what a good muffler would be, thanks.

 

the one thing you forgot to tell us is if it's single tail pipe or duels. if duels I'd go with either flowmasters or glass packs both sound fairly good without having to spend too much money and you get them at any parts house.
