Tunes are popular, available from several vendors and are under $2k all in usually.
An intercooler is a good first step for performance since the I/C is marginal for the Rap.
if you’re not ready for a tune (mechanics will know you tuned it, and warranty could be an issue), pedal commander dramatically improves throttle response, especially in normal mode.
speakers are a great upgrade. If you only spent $15 per speaker, you’d get better sound than what comes out of the Sony/B&O factory speakers. if sound is a thing for you, don’t skimp and do the doors and tweets. It won’t make much diff. right away but when you add the sub, amps and DSP, you’ll be ready for the extra power. ~$2500 or so? depending on your taste and you can do it piece meal if needed.
Backup lights: you can go cheap amazon knock offs, or full on B/D brights. They conveniently put holes right next to the tow hooks to facilitate rear facing lights.
gear for using the Rap off road is always a good idea too; at least first aid kit, recovery straps, air compressor, some cargo securing stuff - tie down straps, maybe the D rings for the bed, or maybe a chase rack.
lots of possibilities under 3-4k.
