Gibson Shorty Headers by , August 26, 2009

Ease of Use/Installation:
Overall Rating:

Went on pretty straight forward. Only issue was they were too close to a metal shroud, made noise. Went back and bent shroud easily. Now perfect, and look real good.

I have not put these on yet. They look great, and the price was certainly right.
