better than original, perfect fit.

100% perfect factory fit, mechanic says this one is better than the original because the mounting holes are separated to allow crack free movement like my old one did.

Pros
  • Exhaust & Emissions
Cons
  • For a long time

The saved heap worked fine.

Discussing whether I wanted to splurge on OEM. But it looks like it's a waste of time if I do it. So it's dormant. Works like a charm, seems identical to AC Delco. But I bought a good set of screws. Because half of my head broke off.

Pros
  • Manifolds
Cons
  • Appearance

Great aftermarket exhaust manifold with all parts needed

This was a great purchase and was a perfect fit to replace my cracked manifold. No problems and a great item at a great price. Be sure to purchase the required exhaust gasket and new mounting bolts. The heat shield was fine and the installation went well.

Pros
  • Replacement parts
Cons
  • Negative gift

The perfect set of the best spare parts

I really liked this kit. Perfect fit at both ends. Great design with gaps between the screw heads to allow for bending so the problem doesn't reoccur, which is typical of the GM 5.3. Will buy this kit again if I need to do the passenger side. Many previous users have said that the head gasket shown in the picture is not included, but it is. Inside the main box is another cardboard insert. The seal is sandwiched between the liner and the outer box so it cannot be damaged. I still ordered the OEM

Pros
  • Automotive
Cons
  • I don't really like it, everything is fine
