ok right now i do not have any cats on my truck and its alil too loud...i was thinking adout a highflow cat would that do better in perforamce or should i leave it with out cats.....i had 2 cats stock and i plan on putting back on a high flow.

 

I say cats...but have them spayed or neutered first

 

cats....your truck will run better...just put in 1 instead of the factory 2

 

Yeah only put one back in for sure, I really dont understand why the put two in you only really need one. Ive been thinking about doing that my self.

 

ide like to remove one of mine but i dont want the emissions light to come on, in New Hampshire if the light comes on you automaticly fail inspection and will not pass unless you have a dealer fix the problem and clear the code

Pretty much my question is, how can i do it, without messing my truck up, and not having a bunch of lights flash at me

 

I don't really see the benefit of removing the cat(s) unless your pushing some bigger HP and Torque numbers. If you got a turbocharger, supercharger, cam, intake and all that good stuff, you'll get some benefit of removing the cat(s) but on a relatively stock engine, I would only replace with a high flow. Keep it legal, keep the low end and keep the sound good.

I think on a relatively stock engine or bone stock engine, it makes the exhaust sound all raspy and obnoxious IMO. To each his own -Mike-

 

these engines like the back pressure a bit i would reinstall a cat on them

 

well.. you definitely need to get one cat on there... but i was thinkin of removing mine and installing one high flow.. and a lot of muffler shops think a lot of doin it... they say its really hard to get in there to weld.... i dont know

 

get a cat on there ... your performance will be better especially becasue you dont have any major mods to the engine .... and the 4.0 needs as much back pressure as it can get

 

you could do a direct fit cat? Magnaflow and Catco make direct fits for these Rangers. Higher initial cost but come with everything you need to bolt it up. Just my $.02 -Mike-

 

I cut 1 Cat off, right after the last sensor, and put a 40 series on it. I've got no engine lights, i got the sound i want, and the power.
