: being the bmw man i am i have invested lots of time and money into my car.. well on that note i got a groupe A header for my car about a year ago.. and well i have not put it on yet simply because of lack of time and so on.. yet i have an option to trade it for some evo3 throtal botties and air horns along with an evo 3 header.. what do you guys think?? with as close as we are to the 100hp per ltr. mark i am told that adding a gp.A header it might make a 5 hp. increase if the motor is tuned right.. and well i might expect the same minor gains from the evo3 stuf as well.. has anybody done this kinda of header swap.. if so how are the gains?? the evo3 parts are brand new so i am sure it cost a pretty penny.. well my grp.A header cost me a fortune and that is no lie either.. so i am up in arms over what to do.. some advice is needed from you guys who have made these decisions already and can help me weigh the gains of the modifications.. thanks..
