5 of 5 Header purchase November 28, 2017
Reviewer: Aaron Smith from Springfield , OH United States  
Well to start off I just want to say how amazing IAG is... I ordered a set of unequal length headers and received equal length... I can't express how amazing the customer service is with these guys!! They were quick to respond with multiple solutions to fix the mix up... ultimately ending with my satisfaction! I will continue to be an IAG customer just for the simple fact that they care about each and every customer that they have... I mean its in their name INTEGRITY!!! These guys rock!!
