Hey all,

My exhaust is pretty much rusted through. Rattles like hell and getting annoying. The question I have is this. The truck has two sets of cats with one set looking like its part of the exhaust pipe itself.

Instead of trying to replace all the rusted clamps and heat shields I was thinking of putting a new system on. Would I run into any problem with a dual pipe setup? I viewed a guy that did a dual pipe in and out of a magnaflow muffler and twin pipe out to the rear. I don't really care much about sound per se, I just figure since its all shot to hell now would be a good time to do something.

Are there any mechanical issues I would come across such as removing O2 sensors or backpressure issues? Thanks in advance for any responses I get.

you can probably find your answer in the exhaust thread.

It sounds like a 2nd generation fronty, therefore you can delete the secondary cats without any issues. From the link above you will see what others have done successfully.

What year and model is your truck? That would be nice to post if you want a better response.

Didn't think to go to the exhaust thread, was around 2 in the morning and I was tired.

I have an 2000 Desert Runner 3.3 (bone stock).
