    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.

    2015 Denali 6.2

    Reviewed By Bill B (New Hartford, NY) Reviewed for a 2015 GMC Sierra —11/17/2016 3:59 AM

    These just added the snap I was looking for from the accelerator you can here and feel the difference in the motor. I partnered this with a K&N 77 series intake and Borla touring exhaust and it brought the 6.2 alive. Better power great sound and picked up 1.5 mpg.
