Smashing! thank's guys!
I used to be an owner of a 2008 E90 335i that suffered from the dreadful turbolag, so when BMW bought back my car because of this i made sure to get the strongest NA model availible - the 330i coupe.
Now, i want to do whatever i can to get the sharpest throttle respons possible, wich performance part will give me that, the intake or the exhaust?
ps. fantastic DIY allan!
