speaking from experience with the GFs cobra..F1s AND F1GSD3s both suck. though the gsd3 is the better of the 2.
just kooks LTs and magnaflow catback the thing would go sideways laying into 3rd at the track. i had to shortshift into 4th to stop the spinning and went 13.2@108.
next time out with et streets she went 12.5@116
