still sounds like exhaust is holding you back....and once you figure out whats truely the problem I would look into SCT

 

no sir, but oddly enough, my build sheet says it has 3.54's tho the tag on the axles and stamp on the ring gear read 3.73... been running that set up since i bought the truck, still running it with the diesel, and same setup in my 75 too...

 

Well here's some video. The first one is me getting on the freeway. I turned onto the on ramp at about 10mph and floored it until I had to stop because of a cop pulled over on the opposite side of the road.

The second video I shot is at a stop sign getting off the freeway on an off ramp. I turned the wheel and floored it. The roads are very course asphalt (slightly wet) but I turned the wheel and floored it. She broke the tires loose very little.

cat, you should have been going faster with those rpm's

 

Thanks point noted,

When it first takes off it gains speed pretty good from what I can see, but then you see that very long very sluggish point after 50 mph. How does your truck act?????


Also, I think I'm going to order a new Magnaflow 12762 muffler and invert it. Gotta check those measurements......LOL http://www.magnaflow.com/02product/d...rtnumber=12762

While it's off, If I hollow out the cat's or pipe between as Dodgetrucker75 pointed out. But I don't want that sulfer smell, I got that when the O2's were removed but have never smelled it before.

Personally, I think it is a blockage. What about the O2 sensors?

 

Front won't care if the cat is gone, rear may cause the PCM to whine about it, but, the non-fouler trick can take care of that, should it become necessary.

 

There is only a front (pre-cat O2 on each down pipe). There is no rear (after CAT) O2 sensor. The system will not know the dirrerence at all.


My question is, will the exhaust stink with the CAT's hollowed out?

 

I dont see why it would stink....I have the V8 and no cat and the only difference I noticed was when sitting at idle there is more of a smell to the exhaust, not a bad smell just not as suttle as before, when driving there is no difference though

A bad smell may come from cracked hoses in the evap system though

 

i know i don't have a ram but did you say this was a built tranny or a rebuilt tranny or a stock original tranny. i know everyone is talking about your exhaust but it actually sounds like a slipping/ worn tranny may only be 4th gear maybe 3rd gear too. sounds like 1st and 2nd gear may still be good and that would be why you accelerate okay enough but once you get to 3rd and 4th gear it falls down. also at that rpms you should be moving faster which is another reason i think your tranny is slipping. have you pulled the trans dip stick and smelled/ felt the fluid?

i have delt with 3 4l60e trans that have done this very thing to a t as you descried. one was even freashly rebuilt by a tranny shop that did a ****ty job on the rebuild.

 

I've always heard that a bad cat smelled like rotten eggs although I don't know why.
