I appreciate everyones' advice. I finally decided on the FRPP GTA's (same as Shelby GT and GT500); 50 state legal and OEM part so hopefully it won't violate the warranty. I'm no mechanic so the removal was a pain in the ass (some really tight and hard to get to bolts). I'm actually proud I got through the installation.
