I have the Williams remap ,librands manifold ,K&N induction system and a side exhaust . I wasn't happy with the performance when the car was new ,I am happy with it now .

I agree with the reply from KEVFITZ. Me and my brother got the AR manifold and 200 cells cat from Cain and went for the remap a few weeks ago. Such a big change. The engine runs very smoothly and revs up very easily to 6000 revs, much more torque in 4th and 5th gear and much faster. I would go for the manifold+cat and the remap by Cain (Wolf Performance). Cain will make you a very nice bacon sandwich while waiting for the remap.
