Magnaflow Catalytic Converter installation?

[nimrodcs]

Just bought a '99 LT 4-Door Tahoe with a 5.7L and had the SES light come on. Ran 4 catalyst system codes, so I checked underneath....

As I thought, a previous owner had cut the cats off and welded in straight pipe. The O2 sensors are still there, but I'm sure they are no good.

Yesterday, I ordered the Magnaflow 23453 Cats along with 4 new O2 sensors and gaskets.

As far as I can see, it looks like a straight forward job, but that leads to my question:

Has anyone done this and had any clearance issues? Does anyting else need to be removed? Any advice is great, cause I really can't find anyting on the net about it.

PS: All the factory exhaust flanges are still there, they were not modified.

Don't have them myself yet for mine but they are a direct bolt on to the factory flanges.

No other removals needed since you have new o2 sensors. May just need to get the vehicle up high enough to pull it out.

Let us know how it goes. I'm planning on replacing mine soon.

I bought the whole Y pipe and cats and it fit great.

Great! Thanks for the input guys. Just waiting on everything to be delivered.

Once I get it all installed, I'll post how it went...maybe some pictures too.

Thanks again.

Is that a direct replacement for a two door as well? Magnaflow list it for a four door only.

I have one on my 2 door, they're available.

Do you have a part number? Is it made by magnaflow?
