Good replacement - collector and parts

Good fit, fittings fit flange. I used Felpro pads instead of the ones supplied. Car started no leaks. Did a few thermal cycles and tightened the manifold bolts. Let's see if the new design holds up.

Pros
  • cool product
Cons
  • Cord is shorter than other picks

Fits for its price

Fits well, castings were a bit rough but that's to be expected for the price. Flange seal holder for Y-pipe, tried 2 different sets

Pros
  • Best in its niche
Cons
  • Poorly designed

Great long lasting product just make sure you buy manifold bolts

Wanted to bring my son's truck in for a replacement they wanted at least 800 so I figured I could handle it myself everything worked smooth, except for one exhaust screw, but i replaced it and did it in a day, saved 700 2004 silverado 2500 hd 6.0

Pros
  • Pleasant
Cons
  • Not bad but...

An exact replica of the original collector. Immediately jumped up.

Exact copy of the original manifold. Bolted right onto my 2006 Yukon 5.3 and got rid of that exhaust noise that a lot of people think is caused by jacks. If your 5.3 has a terrible faucet, the first thing you should do before digging into the engine is to inspect the exhaust manifolds.

Pros
  • Pleasant to use
Cons
  • Easily repairable

Good example from the factory collector.

This appears to be a well made exhaust manifold. It appears to be a direct copy of the latest GM distributor. Supplied with heat shields and manifold gasket on the cylinder head and manifold gasket on the exhaust/catalytic converter already fitted. However, I did not use the header gasket that came with it as it is a fiber material and not stainless steel.

Pros
  • Certified
Cons
  • Secret

Fits well but only time will tell

Looks like Dorman made some changes to this part that appear to be a design improvement. They provided multiple relief cutouts to allow the manifold to flex easily without the disastrous effects of dissimilar metal cycling. (Someone at GM has to sew the legs for this little designer gem. See photo.). Only time will tell if this helps improve bounce rate, but I think it's a good game. AN IMPORTANT CLUE! I installed this on a 2007 6.0L 2500 Silverado. The exhaust donut wasn't big enough. I had to

Pros
  • Handy item
Cons
  • So far so good
