I'd steer clear of the S and B for sure I had one and took it back. It worked good set to stock tune but resonated like crazy on any tune. Resonated loud enough you couldnt carry on a conversation in the cab of the truck. The Gotts works really great I did it with a drop in k and n filter. It performs just as good as the s and b but no resonance.
