Exhaust Question
Have any of your ever put a high flow catalytic converter on your Ranger? I'm thinking about doing it on my 2.3L. If so, how much, did it make a difference in power, and any other opinions or suggestions would be great. Thanks!!!!

what year ranger do you have? I know my stock one did a good job of acting like a muffler. I cut off my old glasspack, and the sound didnt even change when it was coming strait out of the catalytic converter. For the 2.3 you probalby wont get a whole lot more power putting in a high flow in place of your stock one. Unless you like redo your whole exhaust, then put on an intake, chip, electric cooling fan, etc. Then i'm sure that 2.3 would really wind out.

hook up a vacuum guage to your intake manifold, it should be between like 17 and 21 or somthign like that, if your cat is clogged, when you rev it at 2k for a couple of min, it will start to loose vacuum. either that, or look at it at night, is it glowing red hot? if it is, then its clogged. also if it has no power at high rpm.

Your very last resort is what I'm going to do and just save up to buy a new Ranger (with the 4.0...and a new factory cat).

Maticuno- Before you buy a new converter, get youself a couple of really long screw type hose clamps (you know, the kind that go on radiator hoses, but longer). You can screw two together if you have to. Then, put them around the heat shield and tighten. It will stop the rattle. I know, I did it on two different Rangers when the welds that hold the heatshields broke. Works great, costs little!

All i can say is that i'm VERY happy with the mods i've done to my 4.0. Including the exhaust. I cant wait for some cocky kid with a chevy to run his mouth....He'll have his foot in it next. Now all i need are some headers, and i think i'm all modded out.....unless i start tearing into the engine
