I believe you are talking about the downstream tube. It has a check valve at the top that connects to a rubber hose , and then goes down to the converters. If that is what you mean you should be able to get one at any after-market supply store, make sure you get the valve, and the small clamps needed to replace it. it will probably have to be torched off at the bottom near converters.. Hope this helps. :-) Also make sure the head-to-head tube isn't rotted. It runs from one head to the other at the rear of the heads. ;-) Cobra

My 95 oldsmobile cutlass supreme keeps cuttin off and i changed spark plug, coil pak, wires, fuel pump, fuel filter and it still loses power when it wants to

Sounds like you will have to look into your O2 sensors which will be located on the exhaust pipe, as well as your MAF (Mass Airflow Sensor) This will be located on your intake pipe somewhere between your throttle body, and your air box. Those are the only two things I know that can cause intermittent shut down. I sometimes take a can of brake cleaner and spray the sensor on the INSIDE of the intake pipe and it will clean it. Let me know what you find.. Thanks.

My 2001 ford focus runs erratic it idles rough and shifts hard i bought a code reader and the code comes up intake air temperature circuit low input what does that mean?

the iat sensor is included with the mass air flow sensor, there is either a wiring problem or the sensor is dirty, the sensor is located on top of the air box and can be cleaned by spraying some non chlorinated brake parts cleaner on it. try this and see if it helps.

Idle low

Low fuel pressure or clogged catalytic converter. Temporarily remove one of the O2 sensors and take it for a test drive. If the engine accelerates better then the exhaust is plugged (removing the sensor leaves a hole for the exhaust to escape) . Have the fuel pressure tested if it's not a plugged cat.. It could be a weak fuel pump.

I have an '88 ford f-150 302. I changed spark plugs, wires, cap, button, coil, icm module, and o2 sensor. My truck still has no power. I tried to manually set the timing by finding top dead center and...

I have seen this before working for really came down to removing the exhaust pipe infront of the clogged catalytic convertor and road testing it to confirm that the convertor was clogged.. So if you can loosen the pipe in fron of the convertor so that the exhaust can escape with out going through a possibly clogged or melted convertor and if it runs with power thats great other wise diagnostics for the engine will be needed to be done.
