I ordered the product for a 2013 SS. The product arrived ahead of schedule. I would have like to seen the manifold fully welded on the outside and not just in some places. From experience other manifolds have cracked in those places that weren’t welded and caused exhaust leaks, hopefully these don’t have that issue, only time will tell.Driver side installed without any issues.Passenger side however was bit of an issue. I had to unbolt the coil pack bracket to get a bit more space as well as the 10mm that holds the fuel line to the top of the manifold.I reused the oem steel exhaust gaskets from manifold to head on both sides and achieved a perfect seal instead of using the gasket provided as I have seen those leak after time. I couldn’t reuse the oem gasket from the 2 bolt flange to catalytic converters as there aren’t any on the oem side so I had no choice but to use the provided 2 bolt gasket which ofcourse leaked emmediately and I ordered steel 2 bolt gaskets and will replace them emmediately upon arrival.On the passenger side I broke one spark plug upon pushing the manifold down into place but went ahead and installed the manifold anyway and that leads to the next thing, changing spark plugs are virtually impossible to do with these heads with a spark plug socket and ratchet. I had to use a spark plug socket that was capable of being spun with the corresponding wrench, I think mine uses a 17mm wrench. So yes it was pain to change the spark plugs after the fact with using a spark plug socket and wrench to turn the socket as I could not use a ratchet to turn the socket.Onto the next issue, cylinder number 6 definitely requires a spark plug wire that has some type of bend in it as a straight definitely can not be used, I just order a 90 degree set of plug wires so hopefully those work. All other cylinders will work with a straight and thermal heat shielding rated for exhaust manifolds.So all in all I gave it a 4star because of what it could be with a little bit of extra time on the manufactures part to include steel gaskets and also put it in the description which spark plugs wires are required and also to change spark plugs before hand if they haven’t been done in a long time.

Installed these headers on my 2011 Camaro SS. I purchased these headers to keep my factory catalytic converters on the car for emissions compliance. The headers seem to be good quality and installed with no issue. The headers offers more tube length per runner than your typical shorty header. On the dyno the car showed a 14.8 rear wheel horsepower increase over the factory manifolds. Spark plug changes will be a bit challenging and you might want to consider wrapping the headers with exhaust header wrap and also purchase shorter spark plug wires with a 45° boot along with heat shields for the wires. For the money spent for the horsepower gained and keeping the factory catalytic converters in place I am very satisfied.
