09 Silverado 6.2L

Reviewed By Zebulon S (BETHANY, OK) Reviewed for a 2009 Chevy Silverado —3/19/2016 12:01 PM

Pros: Great quality, easy to install if you know what you're doing, added power, sound. Fit 6.2 Cons: better check bolts after driving it repeatedly cause they aren't locker nuts and they come loose easy, had three bolts come off in first week. Needs better directions, Have to get the y pipe welded At a muffler shop Overall, great headers and great quality - made is USA

Awesome Headers

Reviewed By Shawn A (WAUKEGAN, IL) Reviewed for a 2009 Nissan Xterra —3/13/2016 11:55 AM

The Dough Thorley Headers are awesome. They didn't change the sound of my stock exhaust too much, which is what I like, peace and quiet when cruising. Though I love the deep throaty growl at WOT. I only wanted a little more boost in performance, available get up and go power when I need it, from an off-ramp to hauling a full cargo. The Dough Thorley Headers have proven worthy. Also, thank you AutoAnything for a great deal and excellent service.
