Great Replacement Part
Had a pronounced ticking noise when turned on my 2016 jeep patriot. the noise was because of the exhaust manifold leak. this dorman part fit right in and solved the issue. No more exhaust leaks and engine performance has improved noticeably. definitely recommend.

Nissan Exhaust Manifold with Cat no. 1
I got this for my 2004 Nissan Frontier. Looks like OEM but I painted them with Eastwood hi-temp silver prior to putting them on and they look great. No problems so far. Paint adhering well and no discoloration.

Better than the OEM Bolts!
Stronger than the Grade 8.5 originals.

Fits but....
Fit good. Flashing in all ports and the turbo side port was very bad and just crumbled apart. Would have easily broke off and went through the turbo. Had to file and chisel a lot. Ports on block side of manifold were a lot small the the OEM manifold. No gasket for turbo and the studs to short for turbo mount. I had to use the old ones. It did fit and I was able to make it. I would not recommend based on the issues I had. Better studs, better quality control and make the ports the same as OEM and this would be a awesome OEM replacement.
