Need help w/ Magnaflow Catalytic Converter for 99 2 door

[Brewcity]

Hey guys...I am getting conflicting answers from my search. I need to know if this Magnaflow Cat will indeed fit onto my 99 2 door 4x4? :

Any help would be greatly appreciated. If it does NOT...does someone have a part number for one that does?
Thanks again!

23453 for the dual inlet muffler. 93603 if you have a single input muffler. for your state.

Sun...your a life saver! Always willing to help, and right away with the part number and advice! Thanks SO much!
Has anyone bolted this onto their 2 door? How is it, and how hard is it to put on if you have a lift? Also...do I need new O2 sensors? If so, does someone (Sun) have the part numbers for those?
Thanks for the help!

Delphi ES20317 for fronts with a 4l60 installed. Delphi ES20000 for the rear. get all four if installing new cats system. I think bowtie put the cats on his 2 dr.

I have a magnaflow Y pipe and cats. Fit was great. If you are getting the Y pipe and you have a lift you will need to modify the down pipe on the drivers side to clear the front driveshaft.

I am very happy with my setup. I had been going through cats every couple year until I swapped to this

Thanks Sun...I'll pick all 4 up then. I need to do the cats for sure.

Sweet...thanks for the info!

I'll have to go back through some records. Been about 6 years I think

Hey guys. Apologies for bumping an old thread. I'm replacing the midpipe/cats on my 2 door sometime soon. I got under the truck and noticed that I had a single input muffler and Christ, the MF 93603 is ridiculously expensive! Even Amazon is saying over $900. It seems like I saw it just a month ago and it was around $600-700, still considerably more than the dual inlet version. What gives?

How hard would it be to just swap over to a dual inlet muffler?

What year model is this on? Later ones (and I’ll say 96 and up) would have used a two-in single out muffler stock with two catalytic converters.

Mine is actually a 99 leftover. The more I look into it, the more I’m finding out my application is probably stock not for my truck (is for the 4-door) and was changed at some point by a previous owner.

Is it a California vehicle (RPO code NC1)?

Parts diagrams show those using a single-in muffler on the two-door.

Oh wow, thanks! I had no idea. I did observe that RPO on the inside tag had NC1

I'd assume adding a cat back as well would be in order to use the dual-in midpipe?

 

[east302]

I bought this to put on my son’s truck, but the 49-state versions do have the two coming into the flange.

I would assume that the y-pipe connection to the manifolds is the same spacing across CARB certified and 49-state, but wonder if there was a difference in the catalyst itself.

There probably was.

If you’re still in California, it might matter for emissions testing. If not, then I’d wager that you could swap the entire thing out from manifold back. I’d compare the oxygen sensor locations and part numbers just in case.

The funny thing is I'm in Texas. I bought the truck here as well back in 2009. I think I'll begin the process of swapping the catback as well.

Have you considered just taking it to an exhaust shop and having them make you a system?
