If you can find a ZL SLP Car near you, BlackRS, they come equipped with the powerflow's. I like the additional growl from the Loudmouth II's as the powerflow's are more refined. It's like GM's version of exhaust Performance vs. Touring. Both are louder and more noticeable than stock but the Performance is a sportier note. they all fit up the same, just the shape of the muffler is what creates the notes. The LMII's are round cans where as the powerflow's are more like stock sunfire size mufflers long ovals.
