Welcome to the community, Jaime, and congrats on your SHO! Hope it continues to provide you miles and miles o' smiles

What other vehicles have you owned? Pix?
Plenty of mods available for the SHO, esp. the '10-'12:

I do suggest a thorough systems check (spark plugs (should probably R/R), turbo piping, PTU fluid, etc.) before setting about to make mods.
