Thanks for interest ImInPa. I have sold out of all kits. Many are feeling good and all say everything sounds better! Taking orders for next production run. The graph I posted is "Before/After" horsepower at the wheels. While the dyno shows less horsepower at the wheels than anticipated, the measurement of "Before & After" power increase is evident. On my original thread in the Genesis Sedan forum, I posted torque gains. Sorry I don't have that included here on this thread. With so much proof and record sales of "air intakes", it's not a dabate how much a benefit this application is. After exhaust and air intakes, it gets very expensive to get more horsepower.
