5.3 LS Engine differences?
Me and my buddy both have a 2008 Impala SS with the 5.3 LS engine. When starting them up, his has a deeper cranking sound than mine does. Both still have the factory oem starters. Mine has no rear mufflers but his has 2 aftermarket mufflers. Both engine are still stock, just curious why do they sound different cranking over.
