Long Tubes on a 1996, Setup and Convertor Question.
Whoever is running long tubes headers on their 1996, I would greatly appreciate some imput about the setup you are running.
When running, the long tubes, what does one do with the oxgyen sensors and the cat convertors? I ask about 02 sensors because there are four on the 1996. Where do you put the convertors with the long tubes? In the tunnel? Is it possible to setup the exhaust to retain the stock convertors with the long tubes? Just looking for some imput about the topic.
I do intend to keeping the vehivcle emissions legal, so keeping the convertors is key.
Thanks in advance for any imput you may have.

It seems like you have an auto so you need to move the cats where the resonator is. Get bullet cats and they will fit side by side in there. Then you need to buy O2 simulators or move the stockers downstream. You buy the o2 simulators for the sensors that go after the cat. It's a lot of work. That why I went another route. :cheers:

Just out of curiousity Raysur,
What mufflers are you running? By removing the resonator, what did that do to the sound of the car. I was planning on keeping the stock mufflers. Didn't want to make it too loud, but I guess I may not be able to have the cake and eat it to on this one.

If you want to keep the vehivcle emissions legal forget about long tubes. With the A4 there is not room for cats. I TRIED EVERYTHING. It won't work.
As for O2, keep the front 2 bit you cam eliminate the rear 2 but you can do that by PCM programing. No need to spend the money on sims.

Mackey,
This is what I use to have. It did work very well:

I originally planned to have the cats where the x pipe was. But they got moved back. The cats worked fine back there.
The resonator just kills the boominess (new word:lol:) from the exhaust. It does a great job at that too.
