I'm looking at the MagnaFlow Cat Backs, Street vs Performance series.
15153 vs 15154 The difference is the muffler size, otherwise the same, same price.
This is for my 2013 V6
I'm guessing the Performance series will be much louder and possibly not legal (in Nevada)
Any opinions? Or other suggestions?
