swap out your exhaust for rpi section III
- Prefer Remus for quieter sound, needa be wife friendly
ditch the CAI and put in RPI scoop and bmc filter
- used to have K&N filter, so I'd rather keep it
change your plugs, fluids, and belts
- done, done, and done
sway bars
- my car has dynamic drive
Thanks for your suggestion.
