Oh I'm sure those factors came into play. If i had to
guess the FI and Berk Exhausts were dynoed in temperatures that were maybe +50 degrees more than that of the Stillen. (The Stillen info most of us have are from Semtex's result and testing and can be found in his journal.)
I don't want to get too off topic in this thread since it isn't the place for it but yeah....
Props to F.I. for this exhaust, can't wait to see your tunnel video, and video of the straight X pipe!!!!
