Also, I think this is part of the reason their supercharger kit seemed to make such an amazing amount of power to me. Their headers are making much more power than the ~20whp (comparable to mine) that I thought they made, and more like 40-50whp. (between intake exhaust and the headers)

So their exhaust system alone, tuned, gets you relatively close to 300, the s/c kit will then get you the next ~115whp to get to about 400, but I think if I could get close to ~300 N/A that I would probably prefer that, and I could run a small wet shot if I really wanted any more power.
