car already has a X pipe. if you do a short shifter you can do the anti venom mod https://www.ebay.com/itm/Trans-deten...53.m1438.l2649 and do a softer reverse spring to make it feel more like the stock shifter https://www.ebay.com/itm/Soft-Revers...53.m1438.l2649 for a CAI go with the Roto fab big gulp. https://www.roto-fab.com/2017-20-cam...-woiled-filter remove the seondary cats. your not going to gain anything with the exhaust unless you do long tune headers so no use replacing the original x pipe.
