AFE exhaust by waky, August 18, 2008

Ease of Use/Installation:
Overall Rating:

Great value in an exhaust. The description left me wondering if there was enough pipe for a quad cab. The tech rep assured me there was and he was right. Great fit up, read instructions first use jack stands if you have them before cranking down the clamps. I installed on 2001 Dodge quad cab 4X4 Cummins.
