Does anyone have a 2007 with dual pop chargers installed with pics. And are there plenum upgrades avil that make desecent power. lastly other then the intakes and the equal legnth headers what is a significant differance in the HHR that will allow the engine to rev to 7500 vs 6600 or 7100 as in previous engines....
I doubt there are any upgrades for that plenum just yet, but maybe i'm wrong. It would look cool with dual pop's, but not as cool as my dual Greddy intake cones
