    Borla Exhaust on Hummer H3!!
    The exhaust arrived to my home in a matter of 3-4 business days! Borla makes a great looking and awesome sounding exhaust. I purchased this exhaust for my son's Hummer H3 and he loves it! I will be saving up a little for my 2014 Ford F150 now! Borla is a little pricey but well worth it!
