Okay Thanks But

I passed emissions. I didn't expect that since the engine just smells off and lately has been getting 13 MPG.

So My exhaust could use replacing and aside from the legal issues... why don't I just remove the Cat.

Its an 88 ranger 2wd 2.9 Manual with OBD1 so are there any problems with this?

I will give y'all my special 4 x 4 BBQ recipe that's all the rage. Made espeically for those long trips up to those loggin' camps

you could try replaceing the battery cables. i have a 88 that did the same to me and doin that 15 minute low dollar change after several alternators, two starters, and two pick-ups in the distributor, my mileage went to where it is suppose to be and gained a bit of power back. i would start there, and i hope that does it for you, that recipe souds good to me!!!

I will do that... my cables and shit look bad I think....thanks for the tip now back to the cat... I want to take it off if I don;t need it on the next muffler and exhaust replacement... should I and what else should I think about other than legal.

I pass Emissions pretty frequently, smell pretty nasty Too! I try not to talk about these things in public.
Removal of the cat is Illegal so, It also shouldn't be talked about in public. If it were damaged, replace it. A plugged or damaged cat is far worse to the environment then none at all.

well, from what i knowe about cats...the o2 sensor on the 2.9 is after the cat if memory serves right. that allows for the trucks comp to adjust the air-fuel ratio so you don't run to rich or lean...so im my eyes, id say encorporate a high flow universal cat from summit or jegs in the new ehaust system. without it, it might cause your engine to continue to act funky and for the sake of 50 bucks or so..why not. i say keep it in the system.

Aside from the aforementioned legal issues (and the fine is HUGE), you will gain nothing from defeating it, and depending on how you remove it, you can seriously hurt performance. Not to mention we all have to breathe the crap.

And it will not solve your problem. There is no failure mode of the cat that can make your engine run rich. It might be a casualty (eventually), but it's certainly not the cause.

Now this is the type of direct responses I wanted. I wasn't really thinking it would fix anything, but the old one needs to come off and be replaced, and I am past the 20 years in my state so I was wondering if I could and actually how much on these engines can you begin stripping away emissions wise.

That being said, it looks like there is not benefit and cats are cheaper than they used to be. Try getting one on a Jaguar.

Now that I got you on the horn MarG, on this ranger 1988 2WD 2.9 Manual, one of the grounding straps that starts at the windshield wiper moter goes down to the right hand head. On my 1989 Bronco II with the same set up except its a 4x4, the strap connects to the Plenum on the opposite side of the air idle control. WHICH ONE IS RIGHT?

all you're doing is grounding the body to the motor. the principle is that you want everything grounded together, ie: cab to motor, motor to frame so that your electronics work right, i may be wrong but as long as your ground straps are connected to metal it shouldn't matter where you have them, i would think it's just a matter of convenience.
