Stainless Headers Fit For Chevy GMC Avalanche Silverado Sierra Tahoe 00-06 4.8L 5.3L V8

Welds looked great and gaskets sealed well. Will be buying headers for my big block from this company

I really had wished to give my headers 5 stars ⭐️ but I can’t. Everything was looking good until I put the spark plug wires back. Seems like for cylinder 2 the manufacturer of the headers did not take in mind the clearance required for the sparks plug wire and I had to resort to a different style wire. I am a DIY type of guy and I don’t have all the money or time in the world so I had to improvise. This is my daily driver.P.S If the seller agrees to send me the right side header and gasket with the improved adjustments, I promise to pay for delivery fees of any kind, return the defective one and give a 5 star rating.

For the price they’re great but they do hit the steering shaft on 99-07 classic models

These headers fit my 2006 silverado 6.0L v8 with 4x4 without any real problems. The build quality/materials/welds look far better than the price would indicate. I didn't see any pin pricks at all. They bolted onto the mid pipe without an issues and aren't leaking anywhere as far as I can tell. I went and bought my own bolts and a good gasket to meet to the head. No EGR valve hook up, which is nice. I would estimate a 10-15hp gain, but i also did a cherry bomb vortex muffler install as well. Great deal.

👍🏽

Went on a 2000 suburban they fit perfect if needed longer bolts on the right side well worth the money!!

They look great and the welds are nice n smooth so far so good quality for the price

Doesn’t have the EGR hookup so you will have to do an EGR delete which I did and recommend doing, but if you’re not up to that do not buy, also rubs on the steering shaft (for 2wd) so you will have to heat the header and make an indention to clear the shaft. Other than that I noticed power gain and sound difference of course.

Fit was good went in like a dream. Only issue I had was the supplied hardware doesn’t work/fit had to buy felpro manifold bolts and went to hardware store for new flange bolts. All in all not a bad system for the price. Worth the money.
