I notice it's got the Pentastar "loop" in the exhaust.
I noticed that too - it's very common for a VVT V6 engine to have that, they really like equal length exhaust runners. I read somewhere it got the JK Pentaster +20hp.
So if it's not a 3.6 Pentastar, it's very likely a sophisticated VVT gas engine, likely a V6.
