07 yukon headers

[run-gmc]

I'm thinking of installing "Gibson" headers on my 07 Yukon. By installing the after market headers , will the "check engine" light appear?
does anybody have after market headers there Yukon or Tahoe (new body)? If, so how does the suv perform?

Pacesetter longtubes and off road y pipe here. Get a custom tune to turn off the engine light. Noticed a huge difference in performance.
