Rusty lines near front catalytic convertor

[yotadawgjr]

Trying to figure out what the two rusted out hard lines are that hang down near the passenger side frame rail and the front catalytic convertor

I'd like to replace them. They seem to only be rusty near the cat, presumably due to the extra heat contributing to faster rusting. If anyone has a part number, and recommendations on how to deal with them it would be greatly appreciated.

The two lines are horizontal near the cat but then run up to the engine bay next to the fire wall, and are fully vertical when they reach close to the cowl where they both take 90 degree bends and become bigger flexible hoses.

I'm guessing EGR lines??

Rear heater lines going under passenger seat. Loop them off in the engine bay if you don't need it, or replace with flexible coolant hose. Metal part is expensive and the hose fix works fine.

As The Durk suggested or you can still buy new lines as they are SS in the 01 and 02 years.

Toyota part number 87248-35061. Around $100 for those 2 lines assembly.

LOL.. At least you found the part number.

I replaced mine with rubber coolant lines, as the durk suggested. If you go this route, just make sure to zip tie away from the hot exhaust. Otherwise, you run the risk of disaster
