Perfect 5.7 Hemi sound. Not loud, not quiet. Deep low rumble. It is not near as quiet as the stock exhaust that come on the LS engines from the factory, but is not loud either. Great muffler.
Will this fit a 2007 4.8 sliverado 1500? none Magnaflow for a 2006 F150 lariat? I put the 12279 on my Raptor in place of the Roush that came on it. Magnaflow provides a nice mellow rumble with no in cab resonance.
