They come stock with 1.6's.

I am still on the stock manifolds, anything I did internal to the motor would be at about 50% effectiveness until I get that exhaust opened up. This is my daily driver.... its slow as piss and I don't even like racing it. It just so happens its been making a fool out of people lately and that to me is more fun than busting someones ass in my camaro. People expect my camaro to be fast... they don't expect the GTO to leave their super charged 400+ rwhp Cobra in the dust.
no they dont dumbass they come with 1.7's wow king of ls motors huh
