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.

Most Rangers come factory with a high flow cat. But I too am getting ready to replace my cat, mainly because the friggin' heat shield rattles like all get out.

It'll wind out just like you say. BUT it will not help in the normal driving that most of us do. If you change all the intake and all the exhaust features and you don't run the engine at more RPM's then you have accomplished nothing! The intake and exhaust system is engineered to do what most of us do everyday with our trucks. If you don't drive like WE do and you keep your engine at 4,000 or above then maybe you should consider spendingthe money for all these high rpm improvements. However if you spend all that money and DO NOT run the engine at high RPM you will be the loser. The little guy is workin in the range it is supposed to work in...leave it alone.

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.

Problem with this is...these 4 bangers don't have power at ANY 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

Thanks for the advice, but I've already tried this. I even used my torque wrench to get enough leverage to crank the clamp down to no avail.
