Question about Cobra fi2000AT and V&H 2 into 2 combination
So I installed the Cobra FI200AT, the Vance and Hines big radius 2 into 2 exhaust and an LA choppers XXX BAK this weekend. After I got everything on I took it for a test ride (about 120 miles), everything feels good, and it sounds awesome, I did notice some popping and a couple of backfires when compression braking, but I thought that was probably normal.
When I got it home I was looking it over and i noticed some discoloration, (slight bluing?) on the first 4 inchs or so of the front header pipe. Not on the Heat shield, but on the header beneath it.
Has anyone else seen this? or have any thoughts?
My main concern is running too lean. During the exhaust install we tested for leaks, and all seemed good to go.
Thanks in advance!
