i just bought my first 2005 dodge ram 1500 4.7 liter. im loving it so far but i want to make some improvements on it as far as horsepower, better mpg, better exsaust system, etc. if anyone has any ideas, please share.

 

Start with a Cold air intake, I personally like Airaid, but K&N are just as good. You can find them easily on EBay. Then get a Superchip programmer, it really won't give you better mpg, because you have a tendency to stomp on it a lot. The exhaust will give you minimal gains, but they sure do sound cool.
