if your gunna do stacks 5" is what the best looking trucks have...8" is the biggest i would ever think of doing anything after that any your just making up for something like no hp or a small D***:moon:

With stacks the exhaust note isn't bad, it's the "drone" you get at cruisin speeds. A straight thru muffler does wonders for the drone and still sounds good

Where do i get one for cheap?

Ebay or craigslist

I definetley think the stack thing has gotten outa control. I like no bigger than 5" and no more than 1-3" above the cab, but to each there own. The one thing I don't like about them is every hammerhead with a chip or lift in there truck wants to drag race me at every light
