    Gibson Exhaust Performance Headers Reviews

    Great sales experience on a quality product

    Reviewed By Daniel F (North Las Vegas, NV) Reviewed for a 2010 GMC Sierra —8/14/2017 1:33 PM

    Quick delivery of well packaged product. Instructions about preparing to install the headers were great. Complete project took about 6 hours and I was not hurried. These shorty Headers gave my 2010 6L GMC 2500 exactly what I was looking for... about 10% better fuel economy and 5% more mid-range power while towing my RV.
