Wow!!

I was just browsing parts prices for my truck, and found out how much the catalytic converter costs for our Cummins:

List price is $1500.00 !


That is absolutely insane. I sure hope mine does not fail.

 

( EDIT ) Its probably plugged anyway.It will for sure raise your egt and make cooldown on the turbo longer.

Please do not post anything recommending that anyone do anything to these trucks that will violate federal law. Moderator

 

Will these rigs pass an opacity test without it?

 

Im not sure Other guys have said That diesels werent required to have the smog test in some areas where its required ,but I guess its up to your local laws.Im sure someone here will know.

 

Tampering with the exhaust emissions equipment (ie Cat Converter) is against Federal law.
DTR can not condone activity that violates any city, state and/or Federal laws.

Removing the Cat Converter may cause you to fail smog tests, (if your state requires them) and can lead to tickets and penalty fees.

Here's what happens in the Denver emmissions testing district:

They test for exhaust opacity and look for the cat on trucks that had the cat as factory equipment. If opacity fails you can test again (and pay again) after adjusting your smoke. They apparently don't measure HC or NOx so they don't know if the cat is functional or gutted. Truck will NOT pass if they don't SEE the cat in the exhaust pipe. These people are not stupid and their computer tells them which trucks came with OEM cat. They know where to look, but are not required to look inside the cat.

Would a clogged cat affect opacity? I don't know. I have read on this forum that the occasional hard and hot run will clean out the cat. My truck doesn't slow down on the steepest mountain passes so I don't think the cat is clogged yet.

 

yes, you can pass an opacity test... put a throttle stop on the throttle, tighten the AFC all the way and slide the AFC housing back, and slide the plate all the way back... I can't imagine how you'd get a lick of smoke w/ that setting! LOL!

So, how hard are these things to remove and reinstall? I want to see if its clogged or not. Are there 'donut' style gaskets? Any gaskets at all?

I'd have a local exh. shop check, but they charge $$ for that unfortunately.

Reason I ask is that there seems not to be much flow/pressure at the tailpipe when idling, and I'm having power issues. The thing just runs out of steam at 2100 rpm.. In fact, I can't go much over 85 going up a decent hill (freeway..), and 90 is about the limit on a flat stretch. This is all unloaded.

Maybe this is just how these trucks are when stock?


DISCLAIMER: I am NOT suggesting permanent removal of my federally required emissions device, merely asking what is involved with removing and reinstalling it.

 

Dodge has a Cat test pipe....its a pipe that made to be put in place of the Cat Converter to test weather its plugged for power issues.....sorry can't seem to find the part number right now
Disclaimer: this pipe is for testing the Cat only ??

 

I think Dodge quit selling the test pipes, too many people were forgeting to take them off after the test was done.

 

Ya know I am all for the stopping of illegal activity and all that. But this recent change to the rules has got me a little miffed.

If we take the steps to remove this device, I am taking the risk of any fines or other consequenses. Locking all threads, and muting anything to do with 10 year old trucks and emmisions equipment that is failing or causing other engine emmisions problems should be left alone.

It is not the purpose of the moderators or the webmaster to be the police officer of this and I don't expect them to have to perform that duty. If the rules state that the comments and opinions shared on this site may or may not be that of the webmaster, moderators or other non-contributing members then I would think it should be fair game. I respect this site and Jack knows I have gone to bat for the DTR on other sites, but this is a little over the top IMHO.

If that is the case, thenin theory this whole forum should be shut down for Warranty infringements.

My thoughts...

 

Lil Dog, I respect your position on this.
However, I wont get into too much detail here, if you need or want more clarification, please feel free to PM me or Lary.
However, in short, the site rules state (in part)

Lary/Jack are trying to protect DTR from lawsuits/legal action.

Again, if you need more detail, please feel free to PM me or Lary.

Thanks Lil Dog.
Rich.

 

Fair enough guys..

I thought some public clarification would also help others as I am sure I am not totally alone on this one.

Thanks Rich.


PS. I am assuming that some federal officer has contacted the DTR?? If so he/she has about 10 other sites that I know of to visit as well..

Not to sound totally Canadian. But, Lawsuits are synonymous with USA... Frustrating to say the least.

 

But that last line of the rules makes the line VERY grey for the moderators.

I can count about 5 threads right now that may or may not be in that catagory, such as Stacks, or aftermarket exhaust.

This can't be an easy job, but I don't think it makes the site any less likely for that type of thing.

I know, I will PM from here on out..

 

wouldn't the threads about smoking, racing on the highway, or even accelerating through the gears quickly on a public road way be considered similar material in that they are all violations of the law?

and also, the rule doesn't state that you can't talk about breaking a law, it states that the MATERIAL can't break any law... IE, the substance of the post... IE, the letters on the screen.

talking about the effects of removing a catalytic converter is not illegal...

I love this site, but there's a reason I pay $30/yr for TDR.
