Picked up an APEXi drop in filter and Nsidius Industries brake light from a fellow member on the forum. The filter and the TRD green tube is a bit too loud so I've placed the blue sound changer in its place.
Brake light looks good and my car is finally "legal" after removing the third brake light from the rear window.
Edit: Just changed out the 4th brake light bulb to an LED. Colour looks similar to what my tail lights are but I have lost the brake light function and it's basically just a fog light now. Looking into buying a dual function LED make it a brake light again
Don't know which mod to do next because they are so many things that bother me on this car.
