are both catalytic converters included with the Y pipe?

Yes those bumps on the Y pipe are the cats, it's kind of a mother to get in but it's a nice product
1239975
Yes, And my exhaust is sounding nice & my gas mileage is WAAAAAY better. I also replaced all 4 O2 sensors after the install. But it was well worth it to get this cat back system. You won't be disappointed
1239976
Yes. Had No problem installing make sure you change the oxygen sensors. Check and make sure there are two types oxygen sensors if this is for the Chevrolet
1239977
Yes it's a complete y less the O2 sensors. It came with gaskets too. Hope this helps.

No it is for both sensors. Buy the harness and intake gaskets to change at the same time.

No. The oxygen sensor ports are not in this catalytic converter. You either need to use the factory ports or weld on new ones.

The upstream sensor threads into the pipe coming from the engine, closer to the front of the car, and the downstream sensor threads into the catalytic converter, more toward the rear of the vehicle. They are not interchangeable.

i had mine installed by exhaust shop but i believe evrything was included. very happy with the system.

We have a 99' Civic (I think DX if that's the basic model) and this was exactly the right part to replace the catalytic converter. I think the mechanic explained that on this car it is attached to the manifold. I hope it works for what you need. It saved us bank $$$!

Everything in the image is included. The 3 way connector pipe that is included is also part of the redesign that gets rid of the doughnut gaskets and uses a more reliable slip fit connection and flat metal gaskets.

no but make sure you replace both. these are very good quality and a much better price than you could get at a parts store.

On my car it's on/near the rear exhaust manifold within the engine bay. The 2nd sensor is on the catalytic converter. I bought a new sensor just to be safe when I had this part installed.

The exhaust manifold is integrated, which collects to a downpipe. So yes -- you CAN install it.

Absolutely not, a catalytic converter is a fat can that sits right in front of the engine, its job is to convert some of the harmful gasses into harmless gasses. This header is a simple pipe that does no "filtering" at all. And it looks nothing like a catalytic converter. If you're in the state of California or another California emissions state this will not pass inspection. So to answer your question, no this part does not qualify in any way as a catalytic converter.

yes they are included, and installed. It was easy to install, and works great.

This one is placed before the Catalytic converter, on the exhaust manifold. That would be upstream.

Full system exhaust. It is headers all the way back to the muffler. So yes it is a complete pipe and worth every single penny don't just buy the slip on, two different worlds.

I can't speak for your car but as I understand it, upstream is the sensor closest to or before the catalytic converter and others after that are referred to as downstream. Sensors after the cat are not very important and although they might turn on the "check engine" light, they will have no effect on the engine performance, they simply measure emissions. I know some in the know will solder a resistor in to negate the unit so it won't turn the light on. The upstream sensor is the important one. It would seem to me that if the connectors going to the sensor are the same colors then I would install the same sensor whether upstream or downstream. If the wire colors are different, then I would assume that the sensors are different. Hope this helps and good luck. Bob

Y-pipe converter to make it dual exhaust and then some minor bending of the hangers and it should run smoothly over the rear axle like a 4.6 would.

No the upstream (first) O2 Sensor should fit in this header. The downstream (second) sensor is already installed before your other catalytic converter. In order to prevent a check engine light I suggest moving the downstream sensor behind the second catalytic converter if you're buying this header.
