All this for just one question....wow! I just kept reading and reading....I even learned a little about the earth....lol
Anyway Highboy I hope you solved your problem. The only issue I have ever had with Removing a cat is the major exhaust smell. I have put on many off road x-pipes on my mustangs and only had one that gave me a CEL my 2000 GT all I did is bought some Mill elimators from summit and CEL was gone.


UOTE=390Highboy;9200316]Hey, I have a 96 ranger 2.3 5spd and the converter has a rattling noise inside. I want to just take it off because I don't have the money for a new one. But I noticed that there is an O2 sensor behind it. Is that going to cause a computer issue? I dont care if the cel is on, I just don't want a rough running rich or lean burn issue. Anyone have experience with this?[/QUOTE]

 

Ya, I know! I just asked a simple question that required an answer like yours! I DON'T GIVE A HOOT ABOUT FEDERAL LAWS HERE, I just want to know how it affects the performance! But anyhow, that said, I sold the lil bugger about six months ago. I think I regretted that sale more than any other I have ever made. That was the best vehicle I ever owned. I sold it to buy a cherry 69 F100, but the F100 guy backed out of the deal. So I was stuck with no Ranger and no F100. I ended up buying a 67 Stang 6 banger with the money, and I just traded that Stang for a nice 85 Mustang GT 5.0 5spd about a month ago!

 

This whole removing your CAT thing is out of control....have you seen the other threads...lol

The 85 was a good running year.. also last year for the carb. 5.0
It's getting hard to find a nice fox body these days. First thing I did when I got a new stang was put on a offrod x-pipe and a flowmaster cat back with some 373 or 410 gears

 

I took mine out, stock muffler, threw in a simulator that i had sitting around from one of my old mustangs worked like a charm, was also plug n play. also put cold air intake on it. between the 2 im up to 30mpg milking it, and a noticeable power gain. 97 ranger 2.3 2wd single cab 5 speed. gone over 30k miles with this set up problem free.
