What setup are you running?
I still have OEM US sec 1 & 2, thinking of getting a
resonator or two added to my sec 1 like the e46 crowd. I was driving this morning and the noise sounds like it's coming more from sec 1 than the front of the car, which matches what I read on their forum. Will probably get this done and relocate the 02's at the same time, assuming this SES light comes on at some point...
