Excellent quality parts.

Bought these shorty headers for a LS swap into a project vehicle. They worked for me.

Doesn't fit stock vehicle

Weld and material quality seems very good. Figment on oem projects isn't great. Does not fit 2009 Tahoe with 5.3l engine: exhaust manifold bolts provided don't thread into head, header hits fire wall, requires different header to cat flange be welded on, angle of header points exhaust directly into front drive shaft on left side and hits bell housing on the right side. Also I don't think they are designed to be used on engines with spark plugs. I had to buy different plug wires, which still touch the manifold, and I hope won't melt while driving. These headers look cool but don't fit well.
