Smoke Coming From Exaust When Revving

Well bouncing it off the rev limiter at will isn’t going to do you any favors.

If it's oil you'll have more smoke especially at idle.

New exhaust components will always have some smoke as they burn in. Should clear up after it's been fully heat-cycled.

Normal stuff, but the constant revving like that is not to good for your valve train.. Just sayin.. And what acammer said too..

Agreed. Brand new headers and exhaust will definitely smoke a bit until it is fully heat cycled a few times. I notice you listed "ebay" headers, so they probably have some kind of chinesium coating that needs to burn off first.

I could smell the Chinesium from here!
