Performance Intake Manifold
Hey I have a 2011 2SS Auto and I want to eventually put a performance intake manifold. I don’t want to convert my l99 to an ls3. So what are some good intake manifolds that are low profile?

Not worth it on a stock L99. You already have what is recognized as one of, if not the best intake manifolds on an LS engine. L99 redlines at 6200 rpm. Any aftermarket intake is going to need some breathing room to get any appreciable gains, which isn't safely going to happen on a stock L99 due mainly to the rpm limitations of the AFM lifters.
You would be better served rod mod+porting your current LS3/L99 intake manifold. But if you are totally stock, there are better power mods for the money, such as long tubes and tune.
