2007 nbs flowmaster exhuast

[Gregdalueg]

im looking at buying a 2007 silverado ltz 5.3 4x4, and im wanting to put an exhaust kit on it soon, I was looking at the flowmaster outlaw series, but it is only avaliable for the 2009-2013, wheres as the american thunder is for 2007-2013, will the outlaws work on the 2007 or should i just go with a american thunder and change the muffler to the outlaw series one? TIA

Why not just get an Outlaw series muffler and not a full exhaust system? If the inlet 3", it should fit fine.
