just got an email notification today that my tags are due this month and that i need to get my truck emissioned also. it's a 05 so i expected that this year would be the year to get my first emissions tested. i know all they will do is plug into my truck and see what the truck computer tells them.

a couple years ago i put pacesetter lts and y-pipe on. i added high flow cats to that combination but of course left out the rear O2 sensors. i got the truck tuned shortly afterwards but they didn't delete those rear O2 sensors. they have since sold their tuning software. i know there use to be sims i could plug into the sensors but they are pretty much impossible to get now. will the spark plug defoulers route work well enough to trick the emissions computers?

 

I have a similar setup with Magnaflow cats and my 02's are right in the stream and I do not get a check engine light...So for sure in AZ the defoulers will work..or check eBay for 02 sims used...or get a mailorder tune.........

-But I say just put the rear 02's back in as is.....

 

I can't just plop the o2 sensors back in bc the y pipe didn't have the ports for them. So I just unclipped them from the connector near the frame. And I don't want to have to pay to get a mail order tune after I've already had it tuned.

 

Weld in new bungs. Exhaust shops should stock them. If not, you can buy them from Summit or Ebay etc...

 

i have a set of o2 sims i can sell you for cheap if you dont want to put o2's and weld in bungs...

 

Pm sent

 

Without bungs your only option is 02 sims or re-tune...can't use defouers if there is no bung hole..lol

 

You said... oh, never mind.
