You pay a premium for the SuperSprint headers, and to some it's worth it. I can absolutely understand wanting the best, but I don't think there are any performance benefits to be had by going with SuperSprint over Active Autowerke. Just my .02

I'd like to make 100% certain that I can pass emissions drama-free with the AA tune and headers. There is an AA dealer that is ~90 minutes or so from where I live, which is definitely a plus in AA's favor over the Evolve / SS option.
