i love the sound of a performance engine.[i live for it] ive built more than my share,the worst thing a person can do is try to make a stock motor sound like a performance motor through exhaust manipilation.i can hear a mufflar car a mile away.my neighbor did exhaust on his new hummer sounds like its going a hundred but still slow in i laugh every time it starts,same as putting big mufflar on a 5.l mustang.honestly that v-6 sounds like brrrrrumm crap crap crap bruuuummmm crap crap crap sorry not trying to offend noone but someone has to tell you,do heads cam it and exhaust or leave it
