These exhaust manifolds were better quality than the OEM manifolds.
Fit perfectly. Came well packaged, and quite oily, but it dried out over time. Had an extra threaded opening that we didn't use - it came with a plug for that purpose. The gaskets worked out well too.
Decent product for the money. When I received the manifolds there was a piece missing from one of the gasket sets. They were quick to correct the issue and I received a replacement a couple days later with no other issues. Machine work quality was a bit on the lower end, but for the money it's not bad. I would recommend these.
Overall satisfied with purchase. Best price I've seen, fitment is good. Casting is ROUGH, so if you're worried about it, hit them with a grinding stone and sanding drums.
Very good part. Installed about 3 months ago with no issues.
Really great parts really great prices had no problems at all with the fitment or installation will be ordering my parts from here for now on
Fast delivery! Website simple to use!
Everything went fine, the delivery was quick and the parts fit perfect.
The manifolds themselves fit great, and went on without problems, other than the manifold bolts I had to drill out and replace. It was the shipping expectations that disappointed me. When I placed my order on a Monday, the purchase page indicated a 2-4 day shipping time. When I got my email confirmation, it indicated a 3-5 day shipping time. But it was actually the following Monday that I received the manifolds.

I don't remember the brand, but they were installed and everything went very well. Everything fit as expected and it does a great job. I would recommend them to anyone and would buy again for myself. I hope this helps you make up your mind.
