l have a 2004 Dodge Ram 1500 and l wanna make it faster but l dont have a whole lot of money to spend, how should l do it?
its a 5.7 gas
And l allready have flowmaster exhaust on it

is it a 5.9l diesel or 5.8 gas

you can put a cold air intake on it l will give you some horse out like 5-10hp and will might or will get some better mpg

if you have about 250 then l would go with a cold air intake first. if you have about 500 then l would get the cold air intake and then get a cat back exhaust. l put those two items on my 2001 dodge ram 1500 quad cab that has a 5.2 v-8 and l picked up around 10-15 hp and at least 1 mpg. also there is a great improvement in throttle response and it sounds great
