New to Mustangs. GT Manual here, need help.
Originally had a 2011 Chevy Camaro LS auto. Pleasantly modded and ran consistent 13.4-13.5 quarter mile times. Car was totaled in a horrible hydroplane incident and with the money the insurance gave me I purchased a 2013 Deep Impact Blue GT Manual with 30k miles. I couldnt get a camaro to match fords price so that why I transferred to Ford.
Now, the car only has a flowmaster exhaust (While drones like crap but sounds somewhat decent at idle). I ready to mod up. Its my daily driver but I will drag maybe 10 times a year or so. So I want to build a really nice daily driver. I will stay NA. I know the typical mods like cams, longtube headers, tune, maybe a nice CAI, and TB or IManifold but my question is what are the mods that give the best gains. What are the things to start on first? How about common DIY that I need to do since its used?
