Power is the name of the game.
My car with decat pipe and KN panel Filter + cold air pipe gave 89,8 bhp in the rolling road
With Grp A System it revs much faster but Mantzel only quotes +2bhp for the system and +5bhp for the sports cat
So I want some of that power gains and I think the decat pipe is holding the engine a bit, because its standard diameter

But mate,
The car is much faster than the original one. Now you can rev the car till 7200 rpm with power (max power at 7000 rpm), and it revs much faster. I suppose I can get 0-62mph in 9 sec in second gear or less
