I agree... I had the stock exhaust on my F150 replaced with a glasspack and love the sound. It's only loud when I really put my foot in it but for normal driving then it's not bad at all. When I had it put on the guy said it would change my driving habits and he was right . I like the sound and the crackle when the RPM's are dropping but maybe that's just me.
