Our trucks don't sound very good when they are cold. Mine is actually fairly quiet until it gets to normal operating temperature. But anyway, if that was on Yankee's truck I'm sure yours is going to sound totally different. I don't remember what all he had done but I know his 6.0 was built up quite a bit.

 

Stainless sounds tinny anyways until it gets warmed up at least. I love the look and lifespan of stainless but I have to say I like the sound of standard steel tubing better, especially for the money.
