What kind of performance gains are you looking to make?
How much do you want to spend on new brakes? BBK Kits run over $1,500 for 2 piston caliber ones.
Why are you looking to do a full exhaust when you said you had an AFE one installed recently? Headers Arnt worth the ridiculous price tag really. Full carnage exhaust is expensive enough.
How's your maintenance? All fluid changes up to date? How are the rest of the wearable parts like bushings? Rear Shock Mounts?
