Here's the blurb; Is this power increase really likely to be true??? -- cut -- Hyper-Flow Catalytic Converters What can you expect from the Hyper-Flow Catalytic for your 360 Ferrari? o 25% to 30% increase in exhaust flow. o Reduce engine compartment temperature. o No internal parts to corrode. o An average of 30HP increase. o 31.3 HP @ 6,000 RPM o 27 HP @ 4,500 RPM o 36 FT pounds of torque at 4,700 RPM See; http://www.ferraripartsexchange.com/exhaust.htm An extra 30 hp with just replacement cat's? Kinda makes the +20hp that Ferrari gave us with the CS look a little mean if this is true? Can anyone verify whether this is all bull or truth?? I was expecting approx +10hp from cat's but if its this much power it may well be one of the best mod's you can do to the 360 !
