Catalyc Converter

Hey guys I'm new to the mustang word. I'm interested in a buying an 03 mustang v6 from a private owner. The problem that the car has is that it does not have any catalytic converter. How many catalytic converters does the mustang suppose to have because the owner is willing to fix that. I want to make sure he installs at least the stock ones.

Re: Catalyc Converter

If your in an emissions county and are forced to run them for tags then just two will do the trick. Stock they have 4 but two of those are warm up cats so pointless...if youre in a non emissions area then id leave them off

Like he said, all about emissions; if you have them or not.

If the guy leaves 2 on, will the car still run the same cause what about the 02 sensors. And I also think that he welded the pipes to the manifold which I think that it's not correct right?

If he welded the pipes to the manifold don't buy it unless it gets fixed. That will be a HUGE headache

It shouldn't as long as they are proper cats not pre cats. AM Has after market high flows that work well. They also sell MIL eliminates for 79.99 a pair that will keep the light off with a completely catless system. As long as they don't do visual inspections and you like loud throaty exhaust then I would do cats off but that's just what I prefer

you have two o2 sensors (upstreams) and two o2 monitors (downstreams) the upstreams work with the cars computer to help set the air/fuel mix...the downstreams only job are to tell the computer about the catalyst effenciency.

the upstreams are there now or else the car couldn't move in most cases lol (i had one go out while cruising...not fun)

the downstreams may of been cut out by the previous owner. if so when the cats are welded in so will o2 bungs for the downstream sensors. not hard to do for a shop.

also if you want to kill the code for o2 sensors try the non fouler trick. buy a couple spark plug non foulers and bore a 1/2" hole through them (make sure the thread is the same size as your o2's). now put the non foulers in the o2 bungs...then put the o2 monitors into the non foulers other end. pretty much fools the computer everytime about the cats being there

I only see one sensor. It an upstream one. Located on the driver side. And im not if it works. What will happen if I don't install the 3 that are missing? Will it give me low performance? Low gas mileage?

Never mind about what I said before. The owner installed all the 02 sensors. With 2 catalytic converters. He left the manifolds. I'll fix that later on. That shouldn't be a problem right ?

The owner is just going to install 2 catalytic converters, and the 02 sensors. But he is going to leave the same manifolds.

Is ok that the pipes are welded to the manifolds instead of bolted on?
