Exhaust Headers 1-5/8 in. 304 Stainless Steel Polished Finish for 2002-2013 Silverado Sierra Suburban Tahoe Yukon Escalade 4.8L 5.3L 6.0L 6.2L V8

These fit perfectly in my stock 2005 GMC Sierra 5.3L. I wrapped them with fiberglass and sprayed them down with high temp silicone. I ordered short 45 degree spark plugs and barely got the spark plugs in but I think that was the fiberglass boots I added along with all of the wrap that made it difficult. I welded and and removed several broken manifold bolts and installed stainless studs. The temps are way down, the bolts are fixed and I'm sure there's a small power gain.

Good Quality and Fitment on my 4WD Silverado. Been installed now for around 2k miles still look an perform good.

Haven't installed yet but all wells are decent and no leaks were found. Both flames were flat as well. So far i have high hopes.

Fitment was perfect, came with all the bolts and gaskets needed. They sound amazing!! well worth the money for sure

When I installed these I could not get the 3rd spark plug to go in. The exhaust tube bend is too close to the block and curves back right across the spark plug hole. No way to fix it.

Installation was on a 2013 tahoe 2wd. Zero fitment issues, used 45º plug wires. All gaskets sealed and everything lined up.

Very nice. Fast shipping

Put them on a 2004 Silverado 5.3 and love them. Sound great and fit perfectly. Had no issues with 4x4 clearance. You can definitely tell it adds a little low end power.
