Black Dust On Rear Bar

[-=Tyson=-]

Hey there,

Just wondering if someone can tell me what the black dust is on the back of my rear bar and is it something I should be worried about. Im guessing it comes from the exhaust but just wondered if this is normal or not as I have seen a few skylines going around with a black patch on the rear bar near the exhaust.

its a common thing.

you're just running rich. do things like oxygen sensor and plugs/service and you should be right, other than that you'll need a tune.
