I've had a new Milltek exhaust made up for the little Skoda including a diesel sports CAT.
Has given a small power increase and feels alot better top end, now pulls to 130 easy enough (on a private road of course ).
The Turbo Dynamics hybrid turbo goes on monday evening and when mapped should break the 200 bhp barrier and see around 330 340 lb ft torque
Cheers
