Exhaust manifold for my 2006 silverado
The manifold came and was a little different than the original. I had to file some sharp edges off the ports, that were rasor sharp. It fits great. Have to see how it holds up.

Will this replace both sides of the exhaust manifold or just the drivers side ?
Chinobengie on Jun 22, 2017
BEST ANSWER: Just only the driver side.it also has a plate with two bolts sticking up. My original manifold does not have these. Not sure the purpose for it.
