Why is my 2015 5" exhaust so raspy sounding?

[QUOTE="JRLott, post: 1387444, member: 19991"] Truck fires, sounds good, then the hiss comes after about 2 seconds...that's the vanes closing. Mine does it every time. -40, 0, or 100, the truck fire with them open as far as I can tell, then closes them. Truck should warm up better with them closed, which is much more important to you in January, than to me in July. If I lived in CN, I'd leave it...at least during the winter. Me...I'll be looking to get rid of it. Doesn't get that cold down here. This is my understanding from reading here. If I'm wrong someone will be along to enlighten us. [/QUOTE]
