Okay listers, ... the question is whether to backpressure or not to backpressure. Fabspeed GT3 straight pipes or mufflers. Which is going to be faster? I've finally gone to the track with the straight pipes and it would seem the car has less power. Thoughts and opinions please.

(Apologies if you all have been down this road before.)

PS - Has anyone with a 996 motor exchange (MY99) found the new motor lacking in power compared to the first motor?
