I have headers, 2.5" pipe, and 40 seires Flowmasters that just end above and ahead of the rear axle. No turndowns or anything. It sounds really deep, and throaty. But, it is also pretty damn loud, which i like (im 17)

. I like the looks of pipes straight out the back myself, but they sound better inside the cab if you run them out the sides.
