Exhaust Question...
I love the sound of Magnaflow mufflers on the LS3. Will the MagnaFlow 14335 14336 muffler bolt right up (pipe diameter) to a 2012 Grand Sport? Is there any modifying involved in the swap?

Only ONE part number will fit your GS correctly. Check Magnaflow's website. Just make sure you can live with some drone at cruising speeds before buying. Otherwise Corsa is your best bet. Or a used NPP system (cheapest valved option), as well as other valved systems like B&B. Good luck.
