I bolted the Cold air Intake, Exhaust 0 and now Greddy Headers on my XB -
But I now have a little Knock Knock sound coming from underneath at start up and in between 1st and 2nd gear. ( manual tranny)
My headers came with 2 small strips of material one side reflective and the other a white canvas could be heat wrap - but where do they go ? They didnt seem necessary to me so I left them off.
anyone else have this problem of the pipes knocking ? or can anyone help me get rid of it .

THX

Are your shifter cables banging on the new header? When I installed mine they( the cables) needed to be pulled back away from the header, they touched just a bit and made a small "knock-knock" sound.

Just a thought.
