Just in case anyone's thinking about this setup, I installed today and I'm very pleased with both. The high output mufflers are about the deepest sounding pipes I've ever heard. These are big and have a very deep rumble. Sound bites on youtube don't do these justice. Actually the only draw back is the sound resonance these produce giving me a subtle vibration I didn't have with the stock 2010 header and screaming eagle slip on.
