Thanks everyone for answers.
I am from Slovenia, so custom made options are not so good for me.
I want new manifold because i tought that this would give me quite good power gain for this price.
I am new to the cars and "tuning" so I dont know a lot, how to improve car and make more BHP from this engine. So i would ask you if you recomend something different to do with this ammount of money (200-300€).
Thank you very much, Ales
