I have a Supersprint downpipe fitted(standard diameter and still blanking plate but removed first catalyst).
I talked to a Swiss tuner about the different downpipe designs and he mentioned that on his dyno they all differ about 1-2PS.
Thats why he is using the Supersprint (same design as Scorpion).
Now I ask myself if it would be worth for me to change to a Scoobysport or Falkland downpipe?
what do you think ???

I personally think that the power gain comes from removing the catalyst not from the dp design.....???

See other post, but essentially, I was told the removal of catalyst will give BHP, the larger apperture will increase torque (by shifting peak power etc).
