So when I saw not_armed was parting out his car I emailed him and were able to work out a great price on me buying his Milltek and Headers… I went ahead and sold my AWE Catback and 034 HFC’s and made the switch…
In the past 3 years there has been almost no data on these headers and so many claims that they make more power, however nothing to back it up besides one bad 1/4 mile time by Eurocode.
I went out a few weeks ago and gathered some data with the AWE/HFC combo and now today Milltek/EC Headers Combo.
Not only did the headers not do anything but they actually made my car slower.
Here are the before numbers.
DA: -494

0-60: 4.05s
0-100: 9.62s
60-130: 11.9

DA: -1444
Temp: 48 degrees
0-60: 4.16s
0-100: 9.81s
60-130: 12.28s
1/4 mile: 12.64@115.92
