2.5, nothing i hate more then to here a v8 go by going "tatatatatatatatat", 2" makes it sound just like blown72 said, raspy. it wont sound very good at all, like its underpowered and a worn out old 305, lol . get on craigslist and buy some headers from somebody for like $50, at least go 2.25 on your truck, 2.5 sounds real good, nice deep tone.
