Yes, true duals with flowmaster HP2s that exit just behind the cab, so about as straight and clean as you can get.

So maybe a good example for how it performs on hills would be like being in overdrive when you should be down a gear. I have tried down shifting from 4 to 3 but the rpms just rocket up. I can only turn about 3200 - 3400 and the truck is flat out screaming. I need to keep it right at 3000 but, it is almost impossible. Once it drops to 2700ish, all you can do is try to keep moving forward.
