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 manifolds The 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 part And I would recommend getting some spark plug wire covers so they don’t melt against the header they do sit quite close in spots

Got these for an 02 Escalade ext. great quality and well made. Only issue is the gaskets aren’t that good but that’s not a big issue and they don’t have the fitting for the EGR valve so if you plan on keeping that you’ll need something else.

Good fit. I installed from the bottom on drivers side cause I had the exhaust out anyhow. NO you don’t need angled plug wire boots. The boots are long anyhow. Pull the wire back in the boot(wd-40 helps), cut the excess boot off. Use a spare plug as a reference on how much to cut off. I didn’t cut them all off. I used new OEM wires. Don’t buy any thicker wires or you will have problems. Been there,done that.

Fit well,

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.

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.

Well made. Installed these start to finish in about 2 hrs. Everything fits like factory. These make a noticeable power increase, and ive gained about 3 mpg.
