Louder = Better ?

[FlipTrac_511]

If replacing the stock exhaust with a freer flowing one means better performance, and the freer flowing ones subsequently being louder by design, does this mean that louder is better with regards to performance? For instance, would a Flowmaster DF 40, which is louder than the DF 50, yield better mileage and more power of the two?

that's how mine worked out, but for me more performance just happened to be louder. Ask Wayne, he'll back me up.

Not necessarily..........read this tech info. http://popularhotrodding.com/enginemasters/articles/hardcore/0505em_exh/index1.html

I agree with Gary. We went with a FM 70 Series Big Block because I did not want "loud". The AirAid CAI is louder, but combined with the SCTXCal2 it is an awesome combination.

Flip, On a v8 or big block engine I will say yes, But not allways true... Look at the NASCAR setups, Indy and stuff like that. They have "tuned" exhausts. But with the ST any thing is an improvement, And i don't think you will notice anything from on to the other.

You need some type of back pressure....
