I am absolutely sick of the people on the gto forums and how cocky they are. I officially am moving over to the Mustang side (the dark side) haha. I need everyone's help with schooling me on aftermarket parts for the mustang so I can rape any 6.0 liter GTO out there. The 06 GTO's are beasts but I know these new Mustangs have extreme potential to blow them out of the water. I know a tune is a must and less restricting exhaust system. Has anyone added LT headers and mid pipes to their 2011-2012 mustang? If so what brand and what size?
