Doug Thorley Headers

Recommended Posts

I purchased these headers about a year ago and before I could get them installed started having issues with my 2016 Sierra and didnt want to give GM any reason to deny my powertrain claim. I have since had those issues resolved but decided to go a different route with my truck and thus these are for sale. Asking $750 obo plus the ride. Motivated seller as I would like to finish my G8. Thanks. These will fit both the 5.3 and 6.2 of the below listed vehicles. Note if you have the 6.2 you will have to expand the ball at the end of the connection pipe to fit. Thanks again.

 

2014-17 Silverado/Sierra
2015-17 Suburban/Tahoe/Yukon/Escalade

Are there any bolts, gaskets, it hardware included?  Not sure what these normally come with when new.

Everything you need to install is included.

Figures, i was posted at Ft. Stewart for three years, not so much anymore... Send me the total shipped to 49341. I'd rather find a set that I can just bolt on to my 6.2, and Borla stainless cat back.
