My 07 Classic Build

My 07 Chevy1500 Classic , so far all I’ve done is add an 3in RC leveling kit , update the intake to a K&N cold air intake with Sniper adapter plate . Stage 3 Texas sleep cam, Long tube headers to the catalytic converters, connected to a x pipe , 3in exhaust dumped out the side .

I know I’m missing something but that’s the concept so far . Still have a long way to go
