I don't have any welding equipment either, so it should be fun (probably end up going out to buy one and learn how to weld overnight )

WooHoo!!! You're going to love that. That's what I have in my 68. Lose the cats (obviously). OBTW, pick up a couple sets of old tires for the back, just to get that out of your system. You'll be able to spin the wheels for about as long as you want with that thing in there.

LOL. How about I keep the current wheels and tires on there, they're gonna go soon anyways, I hope.

Should I ditch the cats? I don't have money left to buy anything that can replace them.

Ditch the cats and add some o2 simulators. I assume you'r going to get the ecu remapped as well.

Sending the PCM/ECM/ECU/whatever off the be reprogrammed, yep. Those O² sensors are expensive. I want to do something about the exhaust, mines rusting out a bit, I just don't think I'm gonna have the money. The only way I would be able to fork out the money for new exhaust is if the current setup won't fit without me hacking the frame some. I heard that modified vette exhaust will work, but ... haven't seen pictures yet.

How about you just go get a piece of square steel tubing from Home Deopt and weld a small piece of angle iron on it. That's what I did.

Cost me all of 6 bucks.

The engine came with all 4 intact. Don't gotta buy new ones. I'm just saying, they're expensive. Why would I want to get simulators if I've already go the existing ones?

By reprogramming the PCM you will be turning off the rear 02 sensors and therefore will not need the o2 simulators.

I don't think that the F-body manifolds will work for you but you can try. The truck manifolds definatly will not. Removing the Cats will give you some extra power either way OR you can just gut them by taking them off and ramming the guts out (it is a ceramic type of fine honeycomb crap).

Angle Iron? What's that?

Hey, either one of you guys got shots of the underside of your truck while it's up on a lift? I'd love to see your setup (exhaust, crossmembers, etc).

Thanks!

If you remove the cats, you will need the o2 simulators. That was my point earlier.

The point was that HE will not. In general if you do not do any programming you would.

Umm..... see first pic of o2 simulator. Not going to argue the point. He may not "need" it, however his setup also may not perform optimally without.

I know, it needs detailed. The one night I don't put it in the garage, we get a AZ windstorm. Sand everywhere.

no need to argue, I do this for a living. You don't need the rear O2's at all for performance. O2 sims are just a way to keep it from throwing codes with out editing the PCM. They are just for emissions.
Take care.

My understanding (and I could very well be wrong) was that if the ECU/PCM is throwing codes related to o2 sensors, it can/will retard timing and therefore affect performance.

What you are saying then, is that if the ECU/PCU is reprogrammed correctly, the o2 simulators are not needed. "Correctly" being the key term.
Nice truck BTW.

why would i need the O² simulators? can't the O² sensor input just be programmed out of the PCM when it's updated>?

What do you mean? I'm going to mount it on the floor. I posted some pictures from other people's websites who've done the swap for someone else here at hte forum in a recent post. Want the links?

Exactly, that's all I was trying to clarify. The front O2 sensors are needed to monitor the A/F ratio. The rears are not needed as they are just for emissions. When you remove the cats you will need to delete the rear O2s from the PCM and your done - end of story.

Oops, I missed page 2 of this thread.

So, I keep seeing reference to "rear O²'s". There are four of them in plain site from the collector flange to the cats (2 on each side). I take it the one after the cat is the rear and the one closest to the collector flange is the front? What is done about the front one?
