The Scion TC wife bought without me knowing ahead of time ot was a rebuild/salvagedtitle. It was in just messed up shape, inside, wires, connectors, harnesses, airbags, sensors & modules. Took me 3 months of fixing. Painting interior plastics from beige to black. Had effed up rpm surging limp mode 25mph max. Hollowed out the cat, new hoses, cleaned throttle body, no more glowing carry red exhaust headers & no limp mode surging rpms. The sound is still oem quiet which is weird for being hollowed out cat.
