Hard to make a v6 sound like a v8 but this system comes close. I did install the airaid cold air intake with the heartthrob. Did see 2 mpg gain when I wasn't stepping on it. Which is hard because it sounds good. Like most people said only downer is the instructions which is true. Just a little cab noise.
