Exhaust Headers 1-3/4 in. Stainless Steel Polished Finish for 2003-2006 Silverado Sierra Suburban 1500 1500HD 2500 2500HD 6.0L V8

I bought these as a replacement for old rusted exhaust manifoldsThe cost was not much more than the factory style The headers seem very well made and a perfect fit ( remove the inner wheel well lining for ease if access and installation )Removing the old collector bolts and exhaust manifold bolts is the challenging partAndI would recommend getting some spark plug wire covers so they don’t melt against the header they do sit quite close in spots

Awesome. I used it on my 2006 escalade, although they didn't recommend it. Had to get new ignition wires, but for the price, the added work was worth it. They look awesome. And the finish seems to last. If you have a lq9 or similar. Ls1, ls2. They are perfect and half the cost.

fit great, NO leaking and they went in with no problems.

Got a little under 2 years out of them Before they blew apart at the collector. Most likely due to having clogged cats. It has since been deleted and I'm buying another pair of these.

They just fit perfectlyI didn’t have issues with the clocking of the flanges and I always use “ Stage 8” fasteners with heads to keep them from backing out and prevent leaks. I highly recommend these 👍🏻

Well unlike most things on Amazon these work zero issue direct fit 2002 2500HD 6.0 stock ExaustThere is no EGR port on passanger side header but that’s great for me. They have zero leaks all the weld are clean and I have zero complaints and They make the truck a little more snappy . Already got a set on the way for my 2013 .

Not super fancy but they are great on 2004 suburban with 6.0. The gaskets are different than factory so interested to see if they end up leaking but, few months in they work great no leaks. I didn’t notice much power increase from manifolds little on the low end. It also drones just slightly on freeway doing about 75. Overall not bad for the money.

High quality tig welds and great fitment would highly recommend these for anyone having trouble with old stock cast iron manifolds. I put them on my 04 gmc sierra and it runs alot better and sounds great.
