Gibson Stainless Steel Headers Reviews

Was easier than I expected. The instructions recommend removing the inner fender on the passenger side. Instead I removed the battery box which left lots of room to work. The heat shields are attached with hose clamps. I would like to see them use a better system, possibly adding a couple of bolts to the top of the headers to attach shield. The headers have done good job of improving the performance and I would buy them again.
